Abstract: A powered projectile having a nose portion, a body portion, a tail portion, and a central axis. In various embodiments a collar is rotatably mounted to a control support portion with a plurality of aerodynamic surfaces thereon for despinning the collar. An alternator configured as an axial flux machine with a stator arranged can be axially adjacent to one or more rotors, the stator including a plurality of windings and the one or more rotors each including a plurality of permanent magnets arranged about the face of the respective one or more rotor. In various embodiments the projectile includes an assembly of projectile control circuitry. In one or more embodiments, upon relative motion of the rotor with respect to the stator, magnetic flux from the magnets interacts with the windings of the stator and passes through an air gap between the one or more rotors and stator.

Abstract: An aerial rope tramway or slope hoist system suitable for use in an open pit mine or similar application. According to an embodiment, the aerial slope hoist system comprises an upper station and a lower station. The upper station is configured in proximity to a surface section of the open pit and the lower station is configured at a lower section of the open pit mine. According to an embodiment, the upper station comprises first and second towers and the lower station comprises first and second towers. The towers are configured to support respective ends of first and second suspension cable assemblies. Each of the suspension cable assemblies is configured to support and carry a trolley or skip. The system comprises a hoist configured to move the respective trolleys in opposite directions. The towers for the lower station are configured to be moveable and provide the capability to break down the system and/or lengthen or reduce the span of the system.

Abstract: An electronic device may be provided with antenna structures. Proximity sensors and other sensors may be used in determining how the electronic device is being operated. Wireless circuitry such as a radio-frequency transmitter associated with a cellular telephone communications band, a wireless local area network band, or other communications band may be used in transmitting radio-frequency signals through the antenna structures at a transmit power. Control circuitry may adjust the wireless circuitry to ensure that the transmit power is capped at a maximum transmit power. The maximum transmit power may be adjusted dynamically by the control circuitry based on data from the proximity sensors, data from a magnetic sensor that detects whether a cover is present on the device, a connector sensor that detects whether the device is coupled to a dock or other accessory, and other sensors.

Abstract: A system and process for the geo-location of an asset given no a priori knowledge regarding time and location of the asset with minimized power consumption is disclosed. In the preferred embodiment, the system is accurate to about 30 meters CEP (50% circular error probable) using just a short segment, e.g., 100-200 ms, of digitized GPS L1 signal data.

Abstract: The present invention pertains generally to a monitoring system for a resuscitator which detects operation of the resuscitator and includes means for informing an operator of function. The monitoring system is triggered by a pressure signal provided by the cycling of the automatic resuscitator from a controlled inhalation phase to a controlled exhalation phase. The monitoring aspect of the system detects specifically a single point low pressure signals which are sequentially compared against an integrated time clock. Failure of the resuscitator system itself to generate a low pressure signal against the integrated time clock causes an alarm condition.
