Abstract: The present invention relates to heat transfer compositions comprising refrigerant, lubricant and stabilizer, wherein the refrigerant comprises 39 to 45% by weight difluoromethane (HFC-32), 1 to 4% by weight pentafluoroethane (HFC-125), and 51 to 57% by weight trifluoroiodomethane (CF3I), and wherein said lubricant comprises polyol ester (POE) lubricant and/or polyvinyl ether (PVE) lubricant, and wherein said stabilizer comprises an alkylated naphthalene and optionally but preferably an acid depleting moiety.

Abstract: A DVM system is configured to include an incident trigger, which is actuated either manually or automatically in response to an “incident. In response to the actuation of the trigger, an incident identifier is defined. During the period of actuation, a plurality of recordings is automatically made, based on an incident recording protocol. These recordings are all associated with the incident identifier. The automation allows an operator to, at the time of the incident, focus on factors other than ensuring important video evidence is being recorded (such as following a subject through a building by looking at various cameras). The association streamlines subsequent review of an incident, as recordings relevant to the incident are commonly identifiable based on the incident identifier.

Abstract: A significant weather advisory system for an aircraft is disclosed. The system is configured to identify, from strategic weather data, current significant weather events from weather impacted areas projected to be intersected by a geographical corridor around a projected flight path and projected to occur during determined time intervals during which the airborne vehicle is expected to pass through the weather impacted areas; compare the current significant weather events to previously identified significant weather events and detect significant changes between the current significant weather events and the previously identified significant weather events; and generate a notification for display to the flight crew via an onboard notification system that identifies the detected significant change when a significant change is detected.

Abstract: A coaxial gyro accelerometer device in a semiconductor substrate for simultaneously sensing coaxial linear and rotational forces. An exemplary device includes a resonating cantilever beam within a substrate and a package having a resonating cavity. The package supports the substrate while allowing the beam to resonate. The substrate also includes a piezoresistor driver, a piezoresistor sensor, and a semiconductor interferometric optical gyro. The piezoresistor driver and sensor are incorporated within the beam. The driver electrothermally resonates the beam. The sensor piezoresistively senses a signal that relates to an acceleration force out-of-plane of the beam. A waveguide of the semiconductor interferometric optical gyro is incorporated in the substrate around the beam. The gyro senses rotational motion about the axis that is the same as the acceleration vector (out-of-plane of the beam). The gyro also includes a laser source and a light detector.

Abstract: Systems and methods for allowing dual-mode radar operation. An exemplary transmission system includes a hybrid coupler that receives a signal produced by a synthesizer and couples the received signal to two output ports. A pulse transmitter receives a pulse transmit-activate signal from a controller, receives an input signal from the hybrid coupler and, if the activate signal has been received, amplifies the received signal based on a predefined desired pulse output transmission setting. A frequency-modulation continuous-wave (FMCW) transmitter receives an FMCW transmit-activate signal from the controller, receives an input signal from the hybrid coupler and, if the activate signal has been received, amplifies the received input signal based on a predefined desired FMCW output transmission setting. An isolator protects the pulse transmitter during FMCW operation and also the FMCW transmitter from receiving power reflected off of pulse transmitter components.

Abstract: Asset reconciliation is facilitated by dynamically determining and applying a scan context to asset-describing tag data. Tag data representative of assets are received from RFID tags. A working scan context defining a scope of coverage of assets to be included in an asset reconciliation is dynamically determined based on the received tag data. Additional tag data representative of additional assets are received, and the dynamically determined working scan context is applied to the additional tag data to automatically identifying which assets of the additional assets are to be included in the asset reconciliation. Assets included in the scope of coverage of the working scan context are included in the asset reconciliation, and assets not included in the scope of coverage of the working scan context are not included in the asset reconciliation.

Abstract: Apparatus, systems, and methods are provided for dimming pixels on an active matrix light-emitting diode display. One apparatus includes an LED couplable between a voltage source and ground. First and second pulse-width modulation (PWM) drivers are also coupled to the LED. A system includes a plurality of LEDs forming a plurality of rows coupled between a voltage source and ground. A plurality of PWM drivers, each coupled to each of the LEDs in one of the plurality of rows, and a global PWM driver coupled to each of the plurality of LEDs in each of the plurality of rows are also included. One method includes providing current to each LED of a row of LEDs for a first portion of a cycle via a PWM driver, and providing current to each LED in the row for a second portion of the cycle via a different PWM driver.

Abstract: A mechanical architecture for a user interface system enables the use of the low cost commercial load cells. Force inputs to a user interface that is rotatable about two perpendicular axes are reacted in each axis by cantilevered load cells. Two load cells react the loads in each axis, thereby enabling the system to exhibit quadruple redundancy in the load cells.

Abstract: Turbocharger control systems used with electric assist turbochargers include an electric motor for controlling turbocharger operation. The system comprises an oil pressure sensor attached to the turbocharger for sensing oil pressure for lubricating a shaft bearing assembly. The pressure sensor provides oil pressure information to a control system that controls the operation of the electric motor and/or other operating parameters of the turbocharger and/or the vehicle. The control system regulates operation of the electric motor during operating conditions where a low oil pressure condition is detected when compared to a predetermined minimum. The control system reactivates the electric motor once a desired minimum oil pressure has been detected.
