Abstract: A system and method for building and handling oilfield tubular stands while drilling operations are simultaneously and independently occurring with one drilling deck, one derrick, and one rotary system. An offline guided path horizontal to vertical arm lifts and moves in the same plane tubulars stored horizontally on the catwalk and positions the tubulars vertically directly into a preparation hole for assembling and disassembling tubular stands while online drilling operations are simultaneously being conducted. A stand arm lifts and lowers the tubulars into and out of the adjustable preparation hole, and transports the tubulars for storage to an auxiliary tubular racking station in the upper part of the derrick. A bridge racker crane moves tubular stands from the auxiliary tubular racking station to the top drive or another tubular racking station.

Abstract: Example apparatus are disclosed for a wheel-speed tone ring apparatus. An example apparatus includes an axle of a vehicle, and a tone ring coupled to the axle, the tone ring having teeth distributed about a peripheral edge of the tone ring, each tooth having a ramp-shaped surface to be sensed by a wheel speed sensor as the tone ring rotates with the axle.

Abstract: A separator (10, 60, 65, 100) is disclosed for electrically separating groups of end windings (52) in the stator of a rotating electrical machine. The separator is arranged to provide circumferential air channels (24, 74, 85) through the windings. This can allow air flow to be delivered to inside the windings, thereby cooling the windings more effectively.

Abstract: An antenna subsystem receives an analog desired signal, noise, and interference via a communication channel. The desired signal includes modulated encoded digital information. A local oscillator (LO) modulation subsystem generates a modulated LO. The LO modulation subsystem generates a modulated LO to maximize the symbol signal-to-noise ratio of the decoded digital information based on a plurality of: the desired signal, the interference and the noise expected in the communication channel, the characteristics of the converter, and the ability of the DSP to remove the Modulated LO from the converted signal. A mixer mixes the received signal and the modulated LO. A converter converts the mixed signal from analog to digital. A digital signal processor (DSP) removes the modulated LO and desired signal modulation, and decodes the desired signal encoded digital information.

Abstract: A modular device includes a first printed circuit board and a wireless transceiver (e.g., a radio). Electrical connectors (e.g., pads) are located along multiple edges of the first printed circuit board. The electrical connectors are in locations that correspond to a land pattern on a second printed circuit board. Along one edge of the first printed circuit board, the electrical connectors also correspond to electrical connections in a socket. For certification testing, for example, the device can be plugged into a socket. For installation in a host device, the device can be soldered down to the second printed circuit board.

Abstract: Antenna arrays providing high gain during wireless communications are highly desirable for many applications including, but not limited to, multiple-in multiple-out (MIMO) streams and video transmissions. Optimized antenna arrays should also ensure ease of manufacture, thereby enhancing commercial viability. Circular antenna arrays including horn antennas or Yagi antennas are described, each circular antenna array ensuring ease of manufacture.
