IPC: C25B5/00

Abstract: The Vertical Chamber Electrolyser Booster (VCEB) substantially reduces the electrical energy requirement to produce hydrogen gas by water electrolysis. It can be attached to existing electrolysers without modifying the existing electrolyser. The energy saving is achieved by a simple method of controlled release of hydrogen and oxygen gas in two separate chambers that are filled with a liquid and are connected to the gas output of the existing electrolyser. The buoyant force of the released gas will produce torque on turbine blades. This torque drives an electric generator and the generated electric current is used in a secondary electrolyser as input energy. The first released hydrogen and oxygen gases then can be separately collected at the top of the vertical chamber at a marginally reduced pressure.

Abstract: The Video Thumb is a gadget or widget worn on the thumb digit, to protect the thumb from discomfort and indentations of the video game controller. The video game controllers of today are designed, or technically manufactured with cross patterns sharp edges. When the thumb interacts with the game controller on the directional pad, buttons, or analog stick, the indentations cause fatigue and discomfort. The directional pad is shaped like a cross, some game manufacturers have indentations of "rings" on their analog sticks, others have sharp edges, protruding dots, triangular shapes, and small holes built into the design of the video game controller pad. With applied pressure from the thumb to the control pad, the design of the control pad causes blistering and pain when used for extended periods of time.

Title: Cable guided intrusion detection sensor, system and method
Inventor: HARMAN ROBERT KEITH
IPC: H01Q13/20
Filed: 2004-08-02
Abstract: The present invention provides an intrusion detecting system and method for precisely locating an intruder along the length of a sensor cable and for determining the intruder distance from the cable to precisely locate multiple, simultaneously occurring intrusions. The method includes the steps of:  generating a TX signal and transmitting same over a first transmission line of the sensor cable, for creating an electromagnetic field; detecting an RX  signal induced in a second transmission line of the cable by the electromagnetic field and identifying in the RX signal a contra-directional reflection received from a target and a co-directional reflection received from the far-end (F) of the first transmission line, processing the contra-directional reflection for providing a first coordinate (R) of the target, and processing the co-directional reflection for providing a second coordinate (Z) of the target. The method and system may also be implemented with a "true one cable" using a single coaxial cable sensor with a directional coupler for separating coupled signals along a single transmission line in the cable.  Ultra high speed data correlation of the RX signal is achieved through use of a field programmable gate array. The present invention also provides a separate calibrated threshold for every meter of cable to reduce the installation cost associated with meticulous control and the number of cables required for sites with varying burial mediums. In another embodiment, the use of two parallel single cables may be utilized whereby each cable in the system is used to detect and locate intruders independently and more clearly define the direction of crossing and the speed of crossing.

IPC: H04B17/00
Filed: 2006-04-28
Abstract: One illustrative method of scanning a radio frequency (RF) band (e.g. 850 MHz band) for valid RF carrier signals of a wireless communication network (e.g. a GSM  network) includes the steps of monitoring an RF channel to receive a candidate RF carrier signal; identifying whether the candidate RF carrier signal is a valid RF  carrier signal of the wireless communication network by estimating a bandwidth of the candidate RF  carrier signal and, if the estimated bandwidth is different from a predetermined bandwidth associated with valid RF carrier signals of the wireless communication network, identifying that the candidate RF signal is not a valid RF carrier signal of the wireless communication network; and repeating the acts of monitoring and identifying for a next RF channel of a plurality of RF channels associated with the wireless communication network. Preferably, the RF bandwidth estimation is performed together with a system signal detection process (e.g. FCCH detection). Advantageously, the time required to scan the RF band is reduced.
