Title: Non-volatile memory device and method for forming
Inventor: HOEFLER ALEXANDER B
IPC: H01L29/792
Filed: 2003-09-23
Abstract: In one embodiment, a semiconductor device (10) has a highly doped layer (26) having a first conductivity type uniformly implanted into a semiconductor substrate (20), where a channel region (28) is located between a top surface of the substrate (20) and the highly doped layer (26). In an alternate embodiment, a semiconductor device (70) has a counterdoped channel (86) and an anti- punch through region (74) below the channel. A gate stack (32) is formed over the substrate (20). A source (52) and drain (54, 53) having a second conductivity type are implanted into the substrate. The resulting non- volatile memory cell provides a low natural threshold voltage to minimize threshold voltage drift during a read cycle. In addition, a halo region (46), having the second conductivity type and implanted at an angle in the drain side, may be used to assist in hot carrier injection which allows a higher programming speed.

Title: Current integrating sense amplifier for memory modules in rfid
Inventor: CRAIN ETHAN A
IPC: G01R19/00
Filed: 2003-10-14
Abstract: A low read current, low power consumption sense amplifier well suited for low frequency RFID systems is disclosed. An MOS transistor receives the read current from a memory cell, typically an EEPROM, and a current mirror is formed by a parallel MOS transistor. The mirror current is integrated on a capacitor after the charge on the capacitor is cleared via a reset pulse. A time period is defined during which the voltage on the capacitor is compared to a second voltage. The second voltage is formed from a reference voltage or from dummy cells, in either case the reference voltage is at about the logic boundary between a one and zero stored in a memory cell. A comparator, io with or without input hysteresis, receives the voltage on the capacitor and a second voltage and within the time period, the output state of the comparator indicates the binary contents of the memory cell.

Title: Wireless network system for efficiently delivering multimedia messages
Inventor: SHAO XIAOLING
IPC: H04L12/70
Filed: 2003-11-24
Abstract: The present invention provides a wireless network system that enables direct wireless delivery of a multimedia message from a first MMS user agent to a second MMS user agent. In accordance with one embodiment of the invention, the wireless network system includes a MMS server that receives, from the first MMS user agent, a request to send a multimedia message to the second MMS user agent. The request includes an identification (ID) number of the second MMS user agent. From a core network, for example, the MMS server obtains an Internet address of the second MMS user agent based on the ID number of the second MMS user agent, if the ID number is not an Internet address of the second MMS user agent. Then the MMS server forwards the Internet address to the first MMS user agent to enable the first MMS user agent to wirelessly deliver the multimedia message directly to the second MMS user agent using the Internet address. Therefore, by not involving a MMS server in delivering multimedia messages, a substantial amount of network resources is saved, and delivery speed of multimedia messages is significantly increased. As a result, the performance of the overall network system is greatly improved.

Abstract: The present invention is a system and method for restructuring a group of pictures in such a manner as to provide for random access into the group of pictures without substantially degrading the quality of service for the video content. When encoding a current picture, if the current picture is an I picture, the current picture is encoded utilizing intra coding. If the current picture is not an I picture, and is not referenced by future pictures, the current picture is compressed using an arbitrary number of pictures in the past as a reference. If the current picture is not an I picture, and the current picture is not referenced by future pictures, the picture is compressed and the number of reference pictures in the past are limited so that picture prior to the last I picture are not used as a reference. This process continues W1til the conclusion of the group of pictures.

IPC: F25B49/00
Filed: 2004-06-17
Abstract: A transcritical refrigeration system includes a compressor (22), a gas cooler (24), an expansion device (26), and an evaporator (28). Refrigerant is circulated though the closed circuit system. Preferably, carbon dioxide is used as the refrigerant. A fan (54) moves outdoor air that exchanges heat with the refrigerant across the evaporator (28). The speed of the fan (54) is regulated to regulate the evaporator pressure and to adapt the evaporator (28) to different environmental conditions to achieve the optimal coefficient of performance. During high ambient conditions, the fan speed is decreased, decreasing the refrigerant mass flowrate in the system. The energy exchange per unit mass of the refrigerant in the gas cooler (24) increases and the work of the fan (54) decreases, increasing the coefficient of performance of the system. During low ambient conditions, the mass flowrate of the system is low and there is more heat transfer thermal resistance on the refrigerant side at the evaporator (28). The speed of the fan (54) is lowered to decrease the work of the fan (54). Therefore, the coefficient of performance increases.
