Title: Chemical surface deposition of ultra-thin semiconductors
Inventor: SHAFARMAN WILLIAM N
IPC: H01L31/073
Filed: 2002-08-14
Abstract: A chemical surface deposition process for forming an ultra-thin semiconducting film of Group IIB-VIA compounds onto a substrate. This process eliminates particulates formed by homogeneous reactions in bath, dramatically increases the utilization of Group IIB species, and results in the formation of a dense, adherent film for thin film solar cells. The process involves applying a pre-mixed liquid coating composition containing Group IIB and Group VIA ionic species onto a preheated substrate. Heat from the substrate causes a heterogeneous reaction between the Group IIB and VIA ionic species of the liquid coating composition, thus forming a solid reaction product film on the substrate surface.

Title: Method and system for efficient and reliable data packet transmission
Inventor: WEI YONGBIN
IPC: H04W28/04
Filed: 2002-10-02
Abstract: A method and system provides for efficient data throughput by avoiding unnecessary data sub-packets transmission while not missing new data packets.  The method and system distinguishes between a sub-packet for a current data packet and a sub-packet for a new data packet by assigning different codes to them. When a currently received sub-packet and a previously received sub-packet for a previously decoded data packet have equivalent codes, the remote station sends (506) an acknowledgement signal to the base station, preventing unnecessary sub-packets transmission. When the currently received sub-packet and the previously received sub-packet have different codes, the remote station sends (510) an acknowledgement signal, if the remote station can decode the new packet from the current sub-packet. Otherwise, the remote station sends (516) a negative acknowledgement signal to the base station, and requests more sub-packs for the current packet if the limit on number of transmission for currently received sub-packet has not reached.

Patent CA-2468000-A1 (CA)
Title: Modular molding system
Inventor: JENSEN JAMES
IPC: E04F19/04
Filed: 2004-05-21
Abstract: The modular molding system of the present invention comprises a plurality of modular molding sections for covering the joint formed between a vertical wall and a ceiling to create a crown molding. The sections, preferably formed of a thin plastic vacuum-molded material, include an angled faced portion and a horizontal alignment portion interconnected with the angled face portion. The molding sections include a first straight end and a second angled end. The angled ends are used for forming coped corner moldings, the angled end of one section contacting the face of another section at a right angle. A desired length of linear molding is formed by overlapping the straight end of a first section over the angled end of a second section. This process can be repeated to form a molding of desired length. The molding sections are flexible to abut to an uneven surface of a vertical wall. The horizontal alignment portion carries an adhesive which allows the molding to be adhered to a ceiling. The horizontal alignment portion has a dual purpose of providing a surface for carrying the adhesive, as well as providing a means for easily insuring that the molding is properly spaced from a vertical wall.

Abstract: A method for extracting metadata for plural related objects of different types from a database includes defining a heterogeneous object type as a collection of database objects of different types. Upon a request to fetch a particular heterogeneous object, member objects of the heterogeneous object are fetched from the particular heterogeneous object in a specific order based on the definition of the heterogeneous object's type, such as a valid order for re-creating the particular heterogeneous object. The set of member objects to be fetched can be restricted according to at least one specified filter, which itself may be translated into a second filter according to a type of a member object being fetched. Such translated filters can inherit values from the filter specified in the request for the particular heterogeneous object type, or can have a fixed value of some data type.
