Title: Digital video processing method and apparatus thereof
Inventor: SHIN HYUN DOO
IPC: H04N7/26
Filed: 2000-02-03
Abstract: A digital video processing method and an apparatus thereof are provided. The method for processing digital images received in the form of compressed video streams comprising the step of determining a region intensity histogram (RIH) based on information on motion compensation of inter frames. The RIH information is obtained based on the motion compensation values of inter frames, and the RIH information is a good indicator of motion information of a video scene. Also, since the RIH information is quite a good indicator of intensity of the video scene, video streams having similar intensities can be effectively searched by searching for similar video scenes based on the RIH information obtained by the digital video processing method.

Abstract: A beverage brewer (10) comprises a storage tank (14) adapted to contain a supply of liquid, and a metering chamber (16) structured and arranged to be filled with a metered amount of liquid received from the storage tank (14) via an inlet in communication therewith. A brewing chamber (44) is structured and arranged to receive a beverage filter cartridge (46) containing a dry beverage medium. A baffle (30) in the storage tank (14) is shiftable from an open position accommodating liquid flow between the storage tank (14) and the metering chamber (16) via its inlet to a closed position preventing such flow and isolating the metering chamber (16) from the storage tank (14). During a brewing cycle, liquid is delivered from the thus isolated metering chamber (16) to the brewing chamber (44) for combination with the beverage medium contained in the filter cartridge (46). At the conclusion of the brewing cycle, the baffle (30) is returned to its open position, thereby allowing the metering chamber (16) to be refilled with liquid received from the storage tank (14) via its inlet.

Title: Light emitting diode with integrated heat dissipater
Inventor: SHIH KELVIN
IPC: H05K1/18
Filed: 2002-08-19
Abstract: A light emitting diode (LED) has an integrated heat sink structure for removing heat from an LED junction and for dissipating heat from the junction to the ambient air. The anode and the cathode both either act as or are coupled to a thermally conductive material which acts as the heat sink. In one embodiment, the heat sink forms a mounting configuration that allows air to circulate around multiple surfaces to maximize heat dissipation. As a result, the LED junction temperature remains low, allowing the LED to be driven with higher currents and generate a higher light output without adverse temperature-related effects.

Title: Tension measured fishing line bite detector alarm
Inventor: CAMERON MICHAEL JAMES
IPC: A01K97/12
Filed: 2002-08-14
Abstract: A battery powered fishing line bite detector alarm (20) producing visible and/or audible alarm signals is disclosed.      An arm (96), installed within the alarm, integrally connects to a modified leaf on-off switch (66). The alarm attaches to a fishing rod (33) in front of a fishing reel (35) mounted on the rod. Fishing line (38) is threaded into the arm and adjusted such that slack is provided between the rear of the alarm and the front of the reel thereby allowing forward arm movement. The fishing line is further inserted until desired resistance of forward and backward line movement within the arm is achieved. Applied tension to the line forces the arm to actuate. A tension spring clip (84) connected to a switch lever (78), and a common leaf contact arm (76), pulls contact arm closer to an upper common contact point (74) until contact is made activating the alarm signals. Increased tensioning pulls the line through a variable sized slit (110) and into a line hole (100B), releasing tension on the arm and causing the contact arm and contact point to break contact, while allowing the arm to return to a self-adjusting alarm ceasing position.

Title: A blood pressure measuring device with a cuff of two openable concave shell parts
Inventor: DALGAARD TORBEN
IPC: A61B5/022
Filed: 2003-01-23
Abstract: Traditional cuffs for measuring blood pressure use an air chamber enclosed in a non-stretchable fabric to occlude an artery in a limb when supplied with pressurised air. A stethoscope used on the limb is used to monitor blood flow. Application of the cuff is inconvenient and correct placement of the stethoscope chestpiece requieres skill. According to the invention blood pressure measurement is facilitated by having the air chamber enclosed in a pre-formed shell like structure being flexible around the limb and stiff along the limb and by using a linear array of microphones to detect the blood flow noises, the best signal from one of the microphones being automatically selected. Furthermore, the invention provides a facility for correcting the reading in dependence of the amount of wrap of the limb.

Title: Fuel flexible internal explosion gun-engine that converts completely energy of fuel into work or electricity or both
Inventor: HOLUBOWICZ KAZIMIERZ S
IPC: H02K27/12
Filed: 2004-08-12
Abstract: This invention deals with the efficiency of engines. It proposes to replace current combustion with explosions of fuel to eliminate losses of fuel (caused by disintegrations of fuel), improve internal pressure, and eliminate black engine deposits together with emissions of black particulates. The invention proposes to replace the cylinder head of prior art engine with a harmonic oscillator that shields the work-piston from explosions and eliminates excessive stress in crank and related parts. The oscillator is explosion driven. It comprises a gun-device, to explode fuel and convert energy released by explosions into kinetic energy stored in a free oscillating mass. To prevent heat losses, water injections replaced current cooling in this invention. The heat is preserved in the resulting steam and converted to extra work. The conversion does quadruple the efficiency, which cuts fuel consumption and GHG emissions in 80%. In addition, the water injections block NOx synthesis.
