Title: Delay lock loops for wireless communication systems
Inventor: BLACK PETER J
IPC: H03L7/089
Filed: 2002-01-18
Granted: 2006-02-11
Abstract: Techniques for deriving sample timing for multiple signal instances received on multiple antennas for a given propagation path. In one scheme, a DLL is maintained for each path, and each DLL tracks the timing of the best signal instance for the assigned path. In another scheme, a DLL is maintained for each path, and each DLL tracks the average timing of the multiple signal instances for the assigned path. To reduce timing jitter, the SINR of a signal instance may be estimated for a number of different time offsets. The loop filter for the DLL is initially updated in the normal manner. If a change in the time offset used for the sample timing is detected, then the SINRs for the new and prior offsets are compared. The new time offset is used if the associated SINR is better. Otherwise, the prior time offset is retained and used.

Title: Atomic layer deposition system and method
Inventor: CHIANG TONY P
IPC: H01L21/00
Filed: 2002-04-02
Granted: 2003-07-01
Abstract: A deposition system includes a process chamber and a surrounding movable shield that controls a variable gas conductance path. Gas is introduced in a ring surrounding the periphery of a substrate. Gas is introduced into the chamber parallel to the substrate. Gas flux on the substrate is controlled by controlling the conductance of an exit path from the chamber. Ions and reactive atoms are generated for an atomic layer deposition process. A DC bias is created on the substrate to attract ions. A backside gas increases thermal coupling between the substrate and its support. The detection of a chamber pressure change is used to automatically control introduction of reactant gas into the chamber. One reactant gas is used to purge another reactant gas from the chamber. Valves are configured and controlled to selectively introduce gas into the chamber.

On the other hand, data storage drives of an automated data storage library are allocated to received requests. A drive resource provider, upon receiving a request for a drive when all of the drives or the drives of the pool are allocated, holds any mount of a portable data storage cartridge relative to the request, releasing the hold when a drive is allocated. Spare drives are provided, outside of the pool. A spare drive may be allocated in response to the request, and a message is posted indicating use of the spare data storage drive. The posted message may comprise a notification that action may be taken to permanently transfer a spare data storage drive to the pool.

Title: Flow control in network devices
Inventor: BOWEN HOYT EDWIN JR
IPC: H04L12/56
Filed: 2003-10-30
Granted: 2005-12-11
Abstract: Methods and apparatus are provided for controlling flow rates of a plurality of data packet flows into a queue 4 corresponding to a resource 3 of a network device 1. The flows comprise a set 7 of non-responsive flows, and a set 8 of other flows which may comprise responsive flows and/or flows whose responsiveness is unknown. The flow rates are managed in accordance with a queue management scheme such that adjustments are made to each flow rate in dependence on excess bandwidth in the resource, the amounts of the adjustments being dependent on one or more adjustment parameters for each flow. An error signal is generated based on the deviation from a desired allocation ratio of the ratio of the total flow rates into the queue 4 for the sets of flows 7, 8. At least one adjustment parameter for at least one flow is then varied in dependence on the error signal in such a manner as to reduce the aforementioned deviation. A closed-loop control scheme thus operates in conjunction with the underlying queue management scheme to promote fair bandwidth allocation even in the presence of a mix of responsive and non-responsive flows.

Title: Method of fabricating non-volatile memory
Inventor: JENG ERIK S
IPC: H01L21/28
Filed: 2003-12-03
Granted: 2005-09-21
Abstract: The manufacturing method of a nonvolatile memory and its structure is achieved by building a gate dielectric layer on a base. The gate dielectric layer contains at least two layers of different material layers. At least one hetero element is planted on the top of the gate dielectric layer so as to increase the electronic trap density. Then rebuild a new top material after removing the upmost layer of material. Finally, build a gate electrode layer on the gate dielectric layer. In this invention, with the planting of the hetero element, it will form traps in the gate dielectric layer that can catch electrons more easily. Thus, the electrons won't combine together with the increase of operation time. The storage time can be effectively extended and the problem of the combination of bites can be solved.
