****************************

This is the continuation of a photo-project that I began in the summer of 2008: a random collection of "interesting" people in a broad stretch of the Upper West Side of Manhattan — between 72nd Street and 104th Street, especially along Broadway and Amsterdam Avenue.

As I indicated when I started this project in 2008, I don’t like to intrude on people’s privacy, so I normally use a telephoto lens in order to photograph them while they’re still 50-100 feet away from me; but that means I have to continue focusing my attention on the people and activities half a block away, rather than on what’s right in front of me.

I’ve also learned that, in many cases, the opportunities for an interesting picture are very fleeting — literally a matter of a couple of seconds, before the person(s) in question move on, turn away, or stop doing whatever was interesting. So I’ve learned to keep the camera switched on (which contradicts my traditional urge to conserve battery power), and not worry so much about zooming in for a perfectly-framed picture … after all, once the digital image is uploaded to my computer, it’s pretty trivial to crop out the parts unrelated to the main subject.

Thus far, I’ve generally avoided photographing bums, drunks, crazies, and homeless people. There are a few of them around, and they would certainly create some dramatic pictures; but they generally don’t want to be photographed, and I don’t want to feel like I’m taking advantage of them. I’m still looking for opportunities to take some "sympathetic" pictures of such people, which might inspire others to reach out and help them. We’ll see how it goes …

The only other thing I’ve noticed, thus far, is that while there are lots of interesting people to photograph, there are far, far, far more people who are not so interesting. They’re probably fine people, and they might even be more interesting than the ones I’ve photographed … but there was just nothing memorable about them.

If you non-public a laptop computer computer, probabilities are extremely very good that it is possibly powered with a lithium-ion (Li-ion) battery. This battery type has found ask for within of a broad wide variety of customer electronics, which include PDAs and cellular phones. They have gained widespread acceptance as a final result of financial and specialized reasons, especially their significant demand to pounds ratio.

Lithium-ion batteries have transformed the nickel-cadmium (NiCd) batteries that experienced been very first employed to energy laptop computer personal computers furthermore to the nickel-metal hydride (NiMH) batteries that superseded the NiCd laptop computer battery technology. They have dominated today’s rechargeable battery present market for laptop computer personal computers as a final result of the reality they are very much lighter compared to other types of laptop computer batteries, they retain their demand lengthier compared to other modern advances and as a final result of the reality they do not endure away from your storage effect phenomenon. A standard lithium-ion battery has two occasions the vitality density of the traditional nickel cadmium battery. Additionally, lithium-ion batteries possess just one cellular voltage of 3.6 volts as in comparison to 1.2 volts every cellular of nickel-cadmium batteries.

However, the drawbacks associated to lithium-ion batteries include: the chance that the failed battery pack can ignite below adverse conditions, they really are a complete great offer more delicate to significant temperatures environments compared to other battery modern advances within their ability to retain their charge, they may possibly fail if they are completely discharged, furthermore to the inherit chemistry belonging toward battery prospects to degradation with age as opposed toward more powerful correlation in between battery failures and charge/discharge cycles belonging toward more mature battery chemistries. Lithium-ion non-public computer batteries also need that safety circuitry be incorporated in to the battery pack to keep track of the battery demand and also to provide safe and appear voltage and present levels, furthermore to ensuring how the temperatures belonging toward battery persists to be within of a safe and appear working range.

Cylindrical lithium-ion battery tissue are usually tubular in shape, very much such as the issue of traditional alkaline batteries. several tissue are enclosed within of a plastic material real estate furthermore to the man or females tissue are attached within of a method to provide the exact output voltage and also to maximize safe-keeping ability (rated in milliamp-hours). Prismatic shaped lithium-ion tissue are also available, but they are very much more compact and so are generally employed in products just like cellular mobile phones in which pounds and space is acknowledged like a prime consideration.

There are several components that effect the existence of the lithium-ion laptop computer battery. Battery degradation is hastened by heat, so storing the battery within of a awesome atmosphere will prolong its life. producers generally suggest a safe-keeping temperatures of around 60F for that long-term safe-keeping of lithium-ion batteries. These batteries, as stated previously, do not retain a storage from partial discharge cycles, so complete discharge cycles are not required. In fact, partial cycling belonging toward battery will help extend its life. Lithium-ion batteries do possess a limited lifetime such as the more mature battery technologies, but that is pretty impartial of the charging cycles and is also chiefly associated to their age. A standard battery will last only two to three years. that is a fact even once the battery persists to be unused so it is basic to not purchase a substitute laptop computer battery right up until it is ready for getting arranged into service.
