Title: Flexible quantization
Inventor: TU CHENGJIE
IPC: H04N7/24
Filed: 2007-05-04
Abstract: A digital media encoder/decoder uses a flexible quantization technique that provides the ability to vary quantization along various dimensions of the encoded digital media data, including spatial, frequency sub bands and color channels. The codec utilizes a signaling scheme to signal various permutations of flexible quantization combinations efficiently for primary usage scenarios. When a choice of quantizer is available, the codec efficiently encodes the current quantizer by defining a subset of quantizers and indexes the current quantizer from the set.

Title: Crossing guide wire with a corrugated shaping ribbon
Inventor: CHEN HANCUN
IPC: A61M25/09
Filed: 2007-03-13
Abstract: A medical device with a corrugated shaping ribbon is provided, The corrugated shaping ribbon (34) allows for the medical device, which may be provided in the form of a guide wire (20) or catheter, specifically a crossing guide wire or catheter, to more easily navigate through the sometimes tortuous pathways of body lumens In addition, the corrugations (42) effectively provide a mechanism by which energy can be stored as the distal tip of the medical device engages a lesion or other area of occlusion within a blood vessel By storing such energy and continuing to apply force, eventually the distal tip (28) extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.

Title: Draught-resistant fireplace pilot
Inventor: BINZER DAN
IPC: F23D14/74
Filed: 2009-11-05
Abstract: A pilot ignition system for an outdoor gas appliance provides a pilot igniter that is isolated from the ambient wind around the burner by physically distancing the pilot igniter from the burners. The distance is overcome by providing a jet of gas to a nozzle slightly upstream of the pilot, the jet of gas being directed toward the burner. The jet of gas is ignited by the pilot resulting in a torch or jet of flame extending from the pilot igniter through the downstream length of an enclosure to the burner. The jet of flame bridges the distance between the pilot igniter and the burner, while the distance itself isolates the pilot light from wind in the vicinity of the burner.

Abstract: A satellite broadcasts radio programs to mobile and fixed receivers at various locations. Ground stations (220, 320, 620, 720, 820, 1120) supplement the satellite broadcasts in areas where the satellite signal may be shadowed. Likewise, the satellite signal supplements the terrestrial transmissions in areas with marginal terrestrial signal strength. Ground stations (220, 320, 620, 720, 820, 1120) and a satellite (210, 1110) transmit the same digital symbol stream over a same frequency spectrum. The symbol streams arrive in each service area of the ground stations (220, 320, 620, 720, 820. 1120) with a relative delay that is within a window for which a receiver is adapted to decode efficiently. Spectral efficiency is achieved by allowing the ground stations to share the same frequencies as the satellites.

Abstract: The present invention concerns a method of activating or regenerating a hydrogen storage material which contains at least one metal hydride. The at least one metal hydride is brought into contact with an inert solvent and the inert solvent is subsequently removed again.  After contacting with and removal of the inert solvent, there is not only an increase in the reaction rate but surprisingly the hydrogenation also proceeds more completely. The present method is particularly advantageous when the hydrogen storage material contains at least components which interact with one another during absorption and desorption.
