Abstract: A battery monitoring device attached to a vehicle battery includes a battery voltage sensor, motion sensor, location determination module, memory device, wireless modem, and controller. The battery voltage sensor senses the voltage level of the vehicle battery, the motion sensor senses movement of the battery monitoring device, and the location determination module determines the location of the battery monitoring device. The memory device stores a unique identification number associated with the battery monitoring device. Upon detection of an event as indicated by the battery voltage signal or the motion signal or the location information, the wireless modem transmits an alert message that includes the unique identification number and information regarding the event. The components of the device may be encapsulated in a potting compound within a cavity on the battery housing, or they may be enclosed in a housing that is separable from the battery housing.

Abstract: A personal vehicle security device attaches to a personal vehicle secured to a rigid structure using a security cable. The security device includes a housing securely attached to the personal vehicle. The housing has apertures for receiving security cable. Within the housing are one or more sensors for sensing the electrical continuity of the cable, movement of the security device, and location of the security device. A memory device within the housing stores a unique identification number (UIN) associated with the security device. The security device also includes a controller for receiving signals from the one or more sensors and generating an alert message based on an event indicated by the one or more sensors. The alert message includes the UIN and information regarding the event. A wireless modem within the security device housing transmits the alert message from the security device to a wireless network.

Abstract: A system and method to update a patch index such that one or more properties in the patch index are associated with the patch, wherein the patch includes one or more components for the target software system; updating a class path at run-time for the target software system such that the patch associated with each one of the one or more properties supersedes prior patches for the same property; and wherein a component can include a class.

Abstract: An identity state observer for a smooth-rotor permanent-magnet synchronous motor is derived which reconstructs the electrical and mechanical states of the motor from current and voltage measurements. The observer operates in the rotor frame and estimates direct and quadrature stator currents, rotor velocity, and rotor position. Since the rotor position is estimated, the rotor reference frame is approximated using the latest rotor position estimate. The motor dynamics and the transformation into the estimated rotor frame are nonlinear and thus the observer and observer error dynamics are nonlinear. Therefore, small signal stability is analyzed from a linearized model. Simulations including realistic measurement disturbances are used to investigate the global stabilitiy and accuracy of the observer.
