Active firearm safeties have not became a reality because of a limitation in technology. The ability to transmit signals a short distance can be done with IR, RF, sonic and visible light even in a very small size. So an authentication key, ring, badge, holster or other device could be used to release or activate a safety in a firearm. The issues are expense, maintenance, and failure recovery.

This design is an active magazine safety. By incorporating the battery, electronics and a ammunition retaining device into the magazine, there is no need to modify an existing firearm. The electronics can be activated when it senses that the magazine has moved, or removed from a holster, then if the authentication ...

We all know the timed traffic signs with big digital screens. But also most of us get bored when we wait until the count down finish to move our car even though the road is already empty and many seconds are wasted for nothing. What about adaptive times that intelligently adjust the countdown values according to traffic density so we can live happily ever after ?

 The idea is very simple but very effective at the same time. Putting a sensor on the traffic sign that counts passing cars from this point and connects to the next traffic sign with another sensor that also counts passing vehicle. Using a very simple equation we can calculate the count of cars ...

This is an adjustable geometry prone recumbent bicycle. The bike is displayed in its "down" position. At low speeds it is "upright", allowing balance by aligning the riders hips over the pedals and the hands over the front wheel. At speeds over 30 mph, the bike will lower down by use of pneumatic gas springs and allow the rider to maintain a more streamlined position for reduced wind resistance. Braking at using the inertia to raise the bike back up to for low speed maneuvering and stopping. This bike does especially well for hill climbing as well due to the ergonomics of leaning into the hill as opposed to be perpendicularly positio9ned to it with current bike geometry.

My idea is restructuring liquid crystals to have controllable photovoltaic properties. This can cause desirable effects, and could also make photovoltaics much more practical for household use. The panels are designed to exhibit photovoltaic properties when a small voltage is applied from a separate power source, darkening the glass, while also causing the structure to exhibit photovoltaics. When the voltage is removed, the panel resumes transparency. I wish this to be variable. The device functions as a window, shade, and electrical panel at once. Tint would not be necessary on the panels, as the panels can be adjusted for other wavelengths of light. The panels would automate shading, while also generating electricity. They would not need to be installed ...

The new product idea is nicknamed the A-STAR Advanced Superior Tactical Aero Rotorcraft, which has agility control ability via full dimensional thrust vectoring techniques. The A-STAR can be branched from Unmanned Air Vehicle to Manned Vehicle into Safe Air Travel also known as 3 Dimensional Travel. Technologies proposed in this program are to evolve from existing known technologies never before integrated into a full controllable flying vehicle. The proposed propulsion systems start with adaptable engines and the revolutionary Superconductive Electro-Magnetic Propulsion System motors.

Technical Description A-STAR
Mission statement: The Solution Vehicles Co. is to produce the A-STAR Leading edge Aerocraft Vehicles poised for tomorrows needs in Military & Civilian applications with safe, efficient & agile technologies combined for ...

A new concept in the use of integrated Aeolian energy–even for light winds under the speed of 2.5 m/s,-with the assistance of a turbine that has double synchronized rotors with multiple folding palettes of the new type, with auto-regulating in wind and self protection on wind gust (flurry), for the eolian turbines with horizontal ax and also vertical. Thinking a turbine with double rotors provided with semi-rigid pallets made of natural fiber material or recycled, utilizing more ingenious solution with increasing the dynamic effect due to the adaptability to the force and in the direction of the wind through the control and the continuous modification on the entire length of the continuously variable profile with has hig torque of ...

At the end of 2008 there were around 2 million people living with HIV in Latin America - more than in the U.S., Canada, Japan and the UK combined. While this region has often been overlooked in the past, there is now growing recognition amongst the international community that the HIV epidemics of Latin American countries demand more attention than then have received so far.

No country in the world has experienced a significant drop in HIV prevalence. Affecting millions of people’s lives, HIV and AIDS have had widespread social and economic implications for many countries, and these effects will become more severe as epidemics worsen.

THE INITIATIVE
Overall, HIV prevention efforts have been small-scale, slow, and largely dependent ...

The Air Conditioned Helmet, (two patents issued), is the first and only practical thermoelectric air conditioned helmet. It uses a special woven air flow structure for the inside of the helmet that conveys the conditioned air all over the inside of the helmet to cool or heat the maximum area of the users head. Cooled or heated air is ducted into the rear of the helmet and flow up and around the users head, exiting above the users face to provide cooled or heated air fro breathing. The conditioned air can also be filtered with activated carbon to remove odors, etc.

The miniature thermoelectric system adds only 3 oz. to the helmet weight and the air flow structure adds ...

Water drips from standard Air Conditioner (A/C) units because of condensation, but what if the water was to be collected using an automatic device?

My idea looks at recovering waste condensed water from A/C units that run for several months over the year. In order to do so a device fills a tank with water automatically.

The preliminary tests with a home made A/C water recovery system showed that, an average of 27 liters (7 gallons) of water were produced by a standard home A/C in 1 day. If the A/C runs for 10 months in a year, the waste water may reach about 8000 liters (2,114 gallons).

The tests also showed that the amount of water produced in ...

This gas turbine engine design offers an ingenious solution to the pending energy crisis. It offers an alternative energy solution that emits no greenhouse gas, while balancing the greenhouse effect itself, as the by-product of this engine is very cold air.

The concept is a gas turbine engine that is fueled by air. The system produces energy by allowing the ambient surrounding to do work on it, as oppose to the contrary, as in conventional gas turbine engines. Hence the idealised thermodynamic cycle of the concept is the mirror of the conventional Gas Turbine Cycle (figure 1).

The first phase of the design is the analysis of the concept thermodynamic cycle (derivative of figure 1).
Assumptions:
1. ...
