Patent number: 11031513Abstract: A silicon carbide transistor used as an ultraviolet light sensor. The light sensor is mounted inside a probe for detecting ultraviolet light generated by combustion inside an engine. The silicon carbide transistor generates a light voltage that is converted to a digital signal. The digital signal is used in a feedback loop for an engine control module for real time engine control in operating environments. The silicon carbide transistor is mounted inside a glow plug sized engine probe mounted in the cylinder head and the probe includes a quartz window allowing ultraviolet light access between the combustion chamber and the silicon carbide transistor so that the silicon carbide transistor can be mounted proximate the combustion chamber but behind the cooling jackets inside the engine head.Type: GrantFiled: May 20, 2019Date of Patent: June 8, 2021Inventors: James A.

Patent number: 10352788Abstract: Pre-loaded force sensitive input devices, force sensing resistors (FSR), are formed as a multiple membrane assembly that is capable of detecting low intensity pressure inputs and quantifying varying applications of pressure to the sensor surface. Pre-loading the force sensor elements results in a controlled amount of force between the two substrates causing a constant state of pre-load and eliminating the low-end or minimal pressure signal noise associated with unloaded sensors. Pre-loading the force sensing resistor sensor also enables the sensor to detect removal of low intensity pressure input such as might occur during theft of light weight articles placed in contact with the pre-loaded force sensor. Using an FSR or FSR Matrix Array will enable any handling of protected retail packaging to be detected and identified. A library of “touches” can be established that will yield cutting, ripping, twisting, etc. making the detection of a theft in progress more accurate.Type: GrantFiled: December 1, 2016Date of Patent: July 16, 2019Assignee: Sensitronics, LLCInventors: Franklin N. Eventoff, Justin M. Connelly, James A. Holmes

Publication number: 20190028414Abstract: An improved system and method for communication among clients using multiple messaging types are disclosed. In one example, a client includes at least one brew that interfaces with a module. The module encapsulates a transfer mechanism for sending and receiving messages using a particular message type. The client further includes at least one brewer or patron, but may include many brewers and/or patrons, each of which corresponds to at least one topic. An application using the client can send messages to other clients using a standardized interface provided by all brewers and may receive messages from other clients either from patrons using a standardized interface provided by all patrons or from the brew.Type: ApplicationFiled: July 18, 2018Publication date: January 24, 2019Inventors: James David Walker, Matthew R. Dodge, James A. Holmes, Franky Martin

Patent number: 7313792Abstract: A system and method for improved software servicing by installation of an updated version is provided. Using branch versioning techniques that support multi-branch development and release versioning techniques that support multi-version development, an update package may include updated files for each branch or release version. The least possible version from the update package may be installed to minimize the risk for potential software bugs introduced by the high frequency of changes made to a higher version. Additionally, any fix installed on a target machine running a particular version may be migrated when updating the target machine to a new version without losing the fix and regressing the change. Such an update may be uninstalled by reverse migration of any fixes before uninstalling files from the version update.Type: GrantFiled: September 8, 2003Date of Patent: December 25, 2007Assignee: Microsoft CorporationInventors: Garret J.
