There is a growing scientific consensus that the point of ‘peak oil’ passed around 2011 and that viable global oil reserves will be severely depleted from 2030. The long term future of terrestrial surface transport is electrification but the foreseeable future must involve a cost-effective compromise, using an EV system for ‘town’ driving and an internal combustion engine for ‘country’ driving. The 48V Town & Country Hybrid Powertrain (TC48) is game-changing because it shows how to deliver CO2 and pollution free urban traffic by 2030 - in a way that the average customer can afford without government subsidy.

Say ‘hello’ to EV driving in towns & cities; say ‘goodbye’ to high fuel costs!

This weapon is a double barrel (slide pump) action shotgun that has the capability of holding fifty (50) rounds of 12 gauge shotgun shells in a side-by-side stagger single box magazine.

The primary feeding mechanisms in use today by shotguns are:
1. Under barrel tube or multiple tubes with a maximum capacity of 16 rounds. 2. Single stack magazines, no more than 10 rounds. 3. Drum magazines with capacities up to 32 rounds but the drums are large, clumsy, fragile and expensive to manufacture. The "stagger" magazine has never been used in a shotgun because, when the stagger magazine is successfully used in rifles and pistols, the bullets have a pointed or round point created ...

Idea and process of coupling a photovoltaic cell to a super capacitor of Graphene to charge while the cell is illuminated and discharge during low or no light periods.

This approach is scalable, and provides a better impedance match to the cell, as well as allows for series and parallel connections at a much greater efficiency. The cell can be of any type but thin film is easiest to manufacture with Graphene capacitor incorporated into the substrate.

Nanotube tech would be used to further enhance the conversion spectrum of the PV cell. This approach is unique in that it is a direct incorporation of three technologies into one package, and at the time of manufacture of the ...

A novel flat pressure-sensitive array which underlies a display screen in a device, preferably having the dimensions of a smart phone. In an access control embodiment, the initial procedure would preferably take place in a secure environment: (1) an individual whose identity is known places preferably four fingertips of one hand upon the screen of the device, in a normal manner; (2) the contact points of each fingertip as well as the pressure thereat are measured by a proprietary program; (3) the program resolves each oval tip to a point; (4) the vectors and distances between those points are measured; (5) at least three trial sets of the fingertips of each known individual are taken, utilizing those same characteristics ...

It has been estimated that major amputations occur in one out of 300 individuals in the United States [1]. There were more than 1.7 million amputees in the US in the year 2000 [2]; that number is expected to increase to nearly 2.4 million amputees by 2020 [2]. There are 26,000 [3] upper extremity amputations performed per year in the United States of which 10,000-12,000 [4] would be likely candidates for this two degree of freedom (DoF) wrist unit.

This is the presentation of new prosthetic technology with increased function – an electrically powered wrist providing user controlled concurrent motion in two directions, which can be integrated and function with many commercially available terminal devices and prosthesis designs.

Cancer is the second leading killer of Americans, claiming over half a million lives annually. The most powerful predictor of cancer mortality is its ability to metastasize to distant sites in the body. Much of this spread occurs in blood and lymphatic vessels yet effective methods for studying cells in these environments remain undeveloped. We have designed and fabricated a system capable of growing human cancer cells in a controlled environment similar to that of the human body. Such a system serves as an effective model for cancer metastasis and will allow researchers more experimental control than existing cell culture techniques.

Our device seamlessly integrates with existing cell culture technology. It consists of 96 precision-machined cone ...

An ordinary Edison base LED replacement bulb emulates an incandescent lamp in that it provides omnidirectional light. These are used in table lamps, desk lamps and ceiling fixtures. Purpose made LED lighting, such as strip lamps, provide light over a much smaller solid angle where the light is actually needed. This increases their system efficiency over that of LED replacement bulbs even though the LEDs themselves and their power supplies have approximately the same efficiency as those used in replacement bulbs. The reason that LED replacement bulbs with Edison bases cannot provide just light in the down direction, say is that their rotation is dependent on the details of the socket depth. (We are talking about ordinary bulbs, not ...

Blood pressure is a major indicator of a person’s health and one of the five vital signs to watch. However, unlike other vital signs, abnormal blood pressure can be evidence of a long term illness rather than an immediate one and can be used to predict a cardiovascular disease which is a leading cause of death worldwide.

Although non-invasive blood pressure measurement using cuff-based methods provides adequate data for many applications in medicine. Cuff-based methods have some disadvantages which limit their use in certain clinical situations.

For one, a continuous blood pressure monitoring is not possible since a pause of at least one or two minutes between blood pressure measurements is necessary to avoid measurement errors. Thus, short-term changes ...

A new class of heavily cold rolled and thermally processed (HCR-TP) sheet metals is proposed as a viable low cost alternative to producing light weight vehicles for the transportation industry. Presently, automobile and light truck manufacturers are adapting to rising fuel costs by lightweighting vehicles and making revolutionary changes to powertrains. This new class of materials is based on ferrous and nonferrous sheet metals and alloys that can provide the industry with a highly sought combination of features and properties – light weight, high strength, good formability, and low cost. The new class of HCR-TP materials of choice includes low carbon and low alloy steels that are heavily cold rolled to achieve high strength, and the nonferrous materials of ...

Well-known are Atkinson and Miller cycles. These are cycles with varying compression and expansion ratios. Application of these cycles makes it possible to use working gas energy to a fuller extent.
Suggested herein is a different operation mode of a Diesel engine with varying compression and expansion ratios, when the exhaust valve briefly opens and then closes during the compression stroke. The operation is explained in the following drawings:
Fig.1 – the intake stroke;
then the compression stroke starts (Fig.1b);
further on, the exhaust valve is partly opened with air bleeding from the cylinder into the exhaust path (Fig.1c);
then the exhaust valve closes and the second compression phase starts: fuel is injected into the head-end volume ...
