Portable devices

Female urination devices are marketed towards several distinct groups. For sports and recreation they are sold for camping, traveling, festivals, long car journeys, and any kind of outdoor pursuit where the toilet facilities are absent or less than desirable. Since 2005, numerous female urination devices have appeared on the market. Products come in a variety of designs and materials such as plastic, rubber, silicone and paper; some are reusable and some are disposable. Several devices have been marketed for medical applications, and are sometimes available on prescription. Occupationally, urinary devices are used in the armed forces and other outdoor jobs. Some brands are NATO approved, and are supplied to military personnel. Such devices are used by trans men as "stand-to-pee" devices, or STPs, often to combat gender dysphoria. More discreet solutions such as the "Snee-Kee" are specifically marketed for this purpose. Some stand-to-pee devices mimic the appearance of a penis and double as packers.

is there a portable device that i can use to make cream and butter at the same time?

You can make butter in a jar. Pour heavy cream (do not fill, you need lots of space to slosh around). Close, and shake for a long time. Very portable. I do not know what you mean by "make cream". You mean a cow? They are portable, I suppose, just rather large and need to be fed frequently. And cleaned up after.

How to achieve fast charging with USB PD in portable devices

Today's consumers want to conveniently and quickly charge their portable devices anywhere, whether in a business center or shopping mall or waiting for a flight or train. However, there are many different types of charging adapters and connectors, which can make determining which charger or chargers to have on hand confusing for the end user. If the consumer has to carry multiple different charging adapters for different portable devices-such as phones, tablets, and laptops-it can also be an overwhelming experience (Figure 1). Figure 1 A variety of input sources and adapters can overwhelm end users. The benefits include a reversible plug, higher power when using USB Type-C power delivery (up to 100 W), dual-role power capabilities (can act as a sink or source), and higher data speeds. These benefits are rapidly driving consolidation toward using USB Type-C connectors in more consumer devices. It has the added benefit of drastically reducing e-waste by enabling consumers to reuse charging adapters and cables. Figure 2 USB Type-C connectors may soon become the universally accepted standard. The previous micro-USB connector used by many portable devices allowed for a maximum power of 7.5 W (5 V with 1.5 A). With USB Type-C, portable devices can charge their batteries at twice this power with up to 15 W (5 V with 3 A). However, even though a standard USB Type-C power supply can provide up to 15 W, the end user will rarely be able to fully utilize 15 W with a 5V power supply. This is due to two main factors: • Type-C cable can have a maximum 250 mΩ round-trip resistance, and the device's PCB and connector typically add about 100 mΩ of resistance in series with the cable. This means a 15-W supply providing 3 A at 5 V may only deliver up to 11.85 W (15 W - 3.15 W) of power to the charger due to the IR drop. • Since the fully-charged voltage of a single-cell battery keeps increasing year after year, a 5-V supply creates a "headroom limitation" problem for the charger IC. Consider a device where the battery is in the constant voltage phase. It charges at 4.4 V with a 5-V USB Type-C power supply capable of 15 W, and has the series resistance mentioned in the first example (350 mΩ). In this case, only a 0.6 V drop can exist between the power supply's output and the battery's input terminal. This means the maximum available current is about 1.7 A (0.6 V/0.350 Ω), which equates to about 7.5 W of power. To overcome this limitation, either the total series resistance can be decreased, or the power supply's output voltage can be increased. Since the series resistance is difficult to reduce, USB power delivery (USB PD) provides a method to increase the power supply's output voltage to up to 20 V in order to deliver up to 100 W of power. Even with the limitations mentioned above, standard 15-W USB Type-C power supplies are sufficient for many portable devices. However, devices such as smartphones, tablets, wireless speakers, power banks, and cameras usually have batteries larger than 3000 mAh, and can therefore benefit from faster charging by using USB PD. To provide the higher power output, a USB PD adapter can increase its output voltage above 5 V in accordance with a command from the portable device. The maximum power a USB PD adapter can deliver is usually between 15 W and 100 W, depending on the voltage and current levels. Figure 3 shows USB PD source power rules, which are outlined in the USB PD standards to ensure compatibility among different PD adapters (sources) and devices (sinks). The source output voltage must be at a 5-V, 9-V, 15-V, or 20-V discrete level depending on its power rating, while also allowing for a maximum current of 3 A. It is also possible to increase the maximum current level to up to 5 A, but this requires a special, electrically-marked cable to ensure safety. Figure 3 The source power rules are outlined in the USB PD standard. For example, if the sink device such as a speaker only requires 18 W of power (9 V at 2 A), then any compliant USB PD adapter rated for at least 27 W is guaranteed to meet this need based on the power rules. This means end users only need to carry one USB PD power supply for all of their devices, which is more convenient and cost-effective. For manufacturers, this means it's no longer necessary to bundle a power adapter in the box with their product, which also reduces cost and helps the environment by preventing e-waste. To achieve USB Type-C PD fast charging, a PD controller IC is needed in both the portable device and power supply. The PD controller communicates with the PD adapter to determine how much power is needed by the portable device. The PD controller then checks the loading statuses and safety fault information in the portable device. In addition, a PD controller that supports dual-role port (DRP) allows the consumer to charge other devices from their portable devices, such as charging a phone from a laptop. The portable device then functions like a power bank for added convenience. The charger IC is an important component to implement a successful USB Type-C PD fast charging system. Design engineers looking for fast charging solutions can: • Simplify their designs while enabling universal charging-the ability to charge multiple battery-powered devices with different charging configurations and high input voltages. • Extend battery runtimes and use the maximum battery capacity to enable the best possible consumer experience. • Protect the battery, system, and input adapter from failures. Figure 4 An illustration of a USB PD fast charging solution comprising charger and controller devices. Controllers such as this that provide full functionality and bill of materials (BOM) integration advantages are ideal for portable devices. MP2731, an integrated buck charger IC, leverages USB PD input in charging a single-cell battery across an input voltage ranging from 3.7 V to 16 V. With integrated components, this buck charger gives the flexibility to charge compact, size-constrained, battery-powered devices like speakers, cameras, point-of-sale (PoS) systems, and more. It also provides an I2C interface to program charging configurations flexibly, and monitor the charging status and fault. An ultra-low power consumption charger IC extends the battery's runtime during operation to conserve as much battery power as possible when the application is not in use. To support the DRP of a Type-C connector, the IC can discharge the battery to build a regulated 5 V up to 3 A at its input. In this mode, the Type-C port is a source port that can power external devices like smartphones. The charging process and USB On-the-Go (OTG) operation can be monitored by the integrated 8-bit analog-to-digital converter (ADC). Safety features including a fast-charging safety timer, battery temperature monitoring, over-voltage protection (OVP), and over-current protection (OCP) are also critical for battery charging and system operations. To handle PD fast charging, the charger IC reduces the R of the integrated FETs inside the switching charger to improve charger efficiency at high currents. Figure 5 shows charging efficiency curves for the PD fast charging solution, which has a charging efficiency of up to 91% at a 3-A charging current with 9-V input Figure 5 A view of the charging efficiency enabled by the charging IC in a USB PD fast charging solution. However, portable devices typically need to be as small as possible, which drives the need for a fully-integrated switching charger. • The big problem with fast charging using USB Type-C cables

What Are Some Ways to Keep My Hair Really Healthy?
Use professional shampoo & conditioner. I know it may seem like a rip-off, however all the shampoos like Pantene, Garnier, etc. have a high alcohol content....since the normal pH of your hair is 4.5-5.5, things containing high amounts of alcohol throw your hair all out of whack and cause breakage, split-ends, fly-aways, etc. The reason these shampoos make your hair feel soft is because they contain high amounts of humectants, which are just a cover for how damaging they really are! Another tip is ALWAYS use a thermal protector while applying heat. Heat appliances cause tons of damage to your hair. Usually this is a cream/clear gel you apply before blow drying. Never use a flat iron on hair that is not completely dry!1. Split End Help. ( 10 Points) !!!!!!!!!!!!!!!!!!!!!!?For sure you should get a trim and maybe even cut your hair as short as you are comfortable doing it. You should for no reason straighten or dye your hair. Look for some Garnier Fructis or Pantene shampoos and conditioner for curly hair so that it extra moisturizes it and helps the split ends repair themselves. I say from experience that ppl with curly hair have really bad split ends, which is why we have special stuff in our hair products. The split ends wont magically go away in like a month or a few weeks, but you will see improvement after a while. Oh, and for sure DO NOT PICK THEM OFF!! It will just make it worse. Every two months until your hair is healthy get a trim. just maybe half an inch or an inch will be just fine. Eventually your hair will go back to normal. Good luck with that!.2. Whats the best shampoo conditioner for cheap?clever or V05 are solid inexpensive ($a million) shampoos, yet whilst it is composed of conditioner i could bypass Tresemme ($6) it does an somewhat solid interest. i take advantage of salon shampoo because of the fact i am form of a hair snob, yet I nonetheless use the cheap conditioner. Pantene is undesirable on your hair (too plenty protein and reasons alot of greater build up on the hair) so i does not bypass there. desire this permits! My hair is oily, superb, and colour-taken care of if that helps you any!3. How can I get my curly hair to be nice like Taylor Swift?Haha i have the same hair long and curly..but not pretty curly! im completely obsessed with taylor and her hair so i did so playing with it and what you really NEED to get is the conair hot sticks!! they are these little flexible curlers and they are not very expensive and i would look like a frizz ball without them!! you can like get them at walmart. anyways what i do when iwear my hair curly is like i get up and get in the shower and wash it and condition it and this may sound weird but dont use a whole lot of conditioner just enough to get it done cause it will help your hair hold the curl the just get out and towel dry your hair till it is just damp and then put a curling mouse in it and frizz serum then finish blow drying it straight! and you know have the curlers on like when your gettin in the shower and then just make sure the little light is on meaning that they are hot enough and then seperate your hair into pretty small peices (if you have really thick hair then you might need to buy two sets cause they only have 14 in them and you use small sections) and then start from the botom of your hair and role it through your hair and pin it together youll see the instructions on how to pin them together and make sure you wrap it all the way to the top of your head and leave them for like 15 or 20 minutes while your finishin gettin ready and then use like a light hairspray about 5 minutes before you take them out then your done. i know this thing was really long but its not that hard lol!!!! hope i helped good luck!!!!!!!!
