Title: Key Identifier Method and Apparatus
Inventor: STANSBERRY WARREN WAYNE
IPC: G01B7/287
Filed: 1996-06-11
Abstract: An electronic key identifier includes first and second opposing surface segment sensors which can be clamped into engagement with the opposite sides of the blade of an unknown key blank. Each side of the key blade includes collinear surface segments separated by one or more recessed segments. Electrical conductors within the surface segment sensors contact the raised surface segments and discharge electrical energy through the grounded key blade. Appropriate electronic circuitry interfaces the conductor of the surface segment sensor with a computer to generate an electronic image of the two key blade sides. By comparing the electrical image of the unknown key blade with a database of electrical images of known key blades, the unknown key can be identified to allow the operator of a key cutting machine to quickly complete the key identification process.

Title: Method to control data flow rate, queuing network node and packet switching network
Inventor: MEURISSE WIM POL
IPC: H04L12/56
Filed: 1997-03-19
Abstract: As long as a queuing network node (Q) is not congested, it returns to the source terminals (S1, S2, S3, S4) transmitting data packets through this queuing network node (Q), upper packet rate values (ER) which are proportional to the actual packet rate values (CCR). The transmit rate of a source terminal (S1, S2, S3, S4) upon receipt of the upper packet rate value (ER), is controlled so that it stays below this upper packet rate value. In thisway, the queuing network node (Q) allows its aggregate input rate to increase in a controlled, smooth way and does not rely on the sources (S1, S2, S3, S4) themselves. Once the queuing network node (Q) gets congested a fair share algorithm is used to determine which source terminals have to decrease their transmit rates and which source terminals are allowed to further increase their transmit rates.

Title: Configuration mechanism
Inventor: ANDERSSON SOFIA BIRGITTA
IPC: G06F9/46
Filed: 1995-12-08
Abstract: The present invention relates to a method of configuring a distributed computer system. The method comprises inputting to the system how much processor capacity is required by each application subfunction executing on the system, and how many processors each application subfunction must run on.  The processors form a Redundancy Domain. All Resources, grouped together in Distribution Units (D.U.), are distributed over the processors in said Redundancy Domain in proportion to the capacity of the processors and taking into account expected load on the processors, the expected load optionally being based on historical data of processor load. A Redundancy Relocation Scheme is created by assigning at least one other processor within said Redundancy Domain to each D.U., in case of a need to relocate a D.U. to other processors due to load imbalances or other malfunctions in the system.

Title: Fluid spray nozzle with trigger hold means
Inventor: PALMER ROBERT
IPC: B05B15/00
Filed: 1995-11-27
Abstract: A trigger having a pawl operates a nozzle valve via a valve stem in a nozzle barrel bore. A spring in the barrel bore normally biases the valve closed. A toothed ratchet lever is pivotally resiliently secured to a trigger guard which protects the trigger from accidental activation. A ratchet tooth in an array of teeth on the lever engages the pawl to hold the trigger in a selected spray position of the valve, the teeth being normally biased disengaged by a second spring. The teeth each have a sharp crest which digs into the trigger in response to the spring bias on the valve stem overcoming the disengagement bias on the ratchet from the second spring. The nozzle is closed by squeezing the trigger to release the ratchet and pawl engagment such that the ratchet lever is pivoted to a disengement position by the second spring. The assembly comprises metal components in contact with hot fluid but which are thermally insulated with an outer casing spaced from the components by an air gap.

Patent CA-2212765-A1 (CA)
Title: Trench field effect transistor with reduced punch-through susceptibility and low rdson
Inventor: HSHIEH FWU-IUAN
IPC: H01L21/336
Filed: 1996-02-07
Abstract: To reduce susceptibility to punchthrough, the channel region of the P body region (104) of a trench field effect transistor is formed in a layer of lightly doped epitaxial silicon (101). As a result, the channel region has less counterdoping from the background epitaxial silicon and has a greater net P type dopant concentration. Due to the higher net dopant concentration of the P body region, the depletion regions on either side of the P body region expand less far inward through the P body region at a given voltage, thereby rendering the transistor less susceptible to source-to-drain punchthrough. To maintain a low RDSon, the relatively high conductivity of an accumulation region formed along a sidewall of the trench of the transistor when the transistor is on is used to form a conductive path from the channel region to an underlying relatively highly conductive layer (103, 102) upon which the lightly doped epitaxial layer is formed.
