Patent CA-2644360-A1 (CA)
Title: Declarative model for concurrency-control across lightweight threads
Inventor: SAGAR AKASH J
IPC: G06F9/44
Filed: 2007-02-21
Abstract: Implementing synchronization among threads in a workflow. A memory area stores a plurality of work items in a scheduler queue. The work items are associated with an activity in the workflow, and each work item is associated with a thread. A processor is configured to assign a synchronization handle to each of the work items. The synchronization handle indicates a particular shared resource to be accessed by the work items. A token value is computed for each work item based on the assigned synchronization handle and the work items in a hierarchy in the activity. The work items are sorted in a synchronization queue based on the token value associated with each work item. The processor sequentially executes each of the sorted work items in the synchronization queue to serialize the access to the particular shared resource and effects a synchronous execution of the threads associated with the work items.

Title: Double layer papermakers fabric with pockets for bulk enhancement
Inventor: PATEL RAE
IPC: D03D13/00
Filed: 2007-03-12
Abstract: A double layer papermakers' fabric that is particularly suitable for forming or through-air drying (TAD) of high bulk tissue and towel product is provided. The fabric includes a single warp yarn system interwoven with three weft yarn systems such that: a first of the weft yarn systems is located on the paper side (PS) surface of the fabric; a second of the weft yarn systems is located on the machine side (MS) surface of the fabric; and the third weft yarn system is located intermediate between the first and second weft yarn systems. The yarns of the first and second weft yarn systems are interwoven with the warp yarn system such that they are vertically stacked with respect to one another in the fabric. The yarns of the third weft yarn system are interwoven so as to be located in a central plane of the fabric that is intermediate of the first and second weft yarn systems, and each yarn of the third yarn system is located in between the vertically stacked pairs of weft yarns of the first and second weft yarn systems. The warp and weft yarn systems are interwoven according to an asymmetric design which provides generally rectangular pockets on each of the PS and MS of the fabric with the yarns of the third weft yarn system forming the "bottom" of each pocket. There may be from about 50 to 750 pockets per sq. in. of fabric, each ranging in depth from about 0.1mm to about 1.0 mm in depth; these pockets impart unevenness to the fabric surface which assists in creating bulk in the sheet formed or conveyed thereon. The fabrics of the invention also offer low sheet contact area, typically less than 30% of the total fabric surface, and generally in the range of from 15% to about 20%. The fabrics are also highly air permeable to ensure good air flow and drainage of the sheet.

Patent CA-2691453-A1 (CA)
Inventor: MCKERNAN DANIEL
IPC: H04L45/17
Filed: 2008-05-27
Abstract: A method and system for providing a network and routing protocol for utility services are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a utility device (for example, a constant powered meter) sends network discovery messages to find the utility network. Neighboring meters are discovered and the device listens for advertised routes for one or more networks from the neighbors. The device is then registered with one or more utility networks, receiving a unique address for each network registration. Also illustrated in this invention disclosure is how each device of a class of devices (for example, battery powered meter) finds and associates itself with another device (for example, constant powered meter). The constant powered meter also registers its associate battery powered meter with the utility networks. The constant powered meter registers itself with the access points and the upstream nodes in the path out of each network. Each upstream node can independently make forwarding decisions on both upstream and downstream packets i.e. choose the next hop according to the best information available to it. The constant powered meter can sense transient link problems, outage problems, a nd traffic characteristics. It uses the information to find the best route out of and within each network. Each network device thus maintains multi-egress, multi-ingress network routing options both for itself and the device(s) associated with it.

Abstract: A hopper for a coin processing machine has a turntable that receives coins and rotates in a first direction to discharge coins from the hopper. A circumferential wall surrounds the turntable, and includes a coin discharge opening and a second opening.  A diverter plate extends away from the wall upstream of the second opening.  The diverter plate blocks coins from entering the second opening when the turntable rotates in the first direction. The diverter plate directs any debris remaining on the turntable to the second opening when the turntable rotates in the opposite, second direction after discharging all the coins from the hopper.
