Abstract: Methods, systems, and apparatuses for presence detection are described herein. A first computing device may emit an inaudible audio signal. A second computing device may detect the inaudible audio signal. The second computing device may send an indication of detecting the inaudible audio signal. The first computing device may cause presentation of content to be modified based on the indication sent by the second computing device and a user profile associated with a user of the second computing device.

Abstract: A privacy label system includes a sheet of label material configured to be removably attached to a container of a product in an unfolded layer configuration. The label material includes a top surface area configured to receive personal information of a recipient of the product and an opposing bottom surface area configured to receive advertising information associated with the product. An attachment system of the privacy label system is operable to removably attach the label material to the container in an unfolded layer configuration such that the bottom surface area is positioned between the top surface area and the container, once the label material is attached to the container. The label material is operable to be removed from the container by the recipient by hand, in order to remove the personal information from the container and to reveal the advertising information to the recipient.

Abstract: A privacy label system includes a single sheet of label material configured to be removably attached to a container of a product in an unfolded single layer configuration. The label material includes a top surface area configured to receive personal information of a recipient of the product and an opposing bottom surface area configured to receive advertising information associated with the product. An attachment system of the privacy label system is operable to removably attach the label material to the container in an unfolded single layer configuration such that the bottom surface area is positioned between the top surface area and the container, once the label material is attached to the container.

Abstract: An audio mixer (20) include a chassis (22) adapted to receive a docking tray assembly (24), which in turn is adapted to receive a computing device (26). The computing device functions to operate and control the audio mixer (20), and to this end includes a touch screen display (28). The docking tray assembly (24) includes formed tray (110) and, optionally, an adapter configured as a formed insert (112) that nests with the tray (110) to dock a computing device of a configuration different from the computing device docked directly with the tray (110).

Abstract: An instrumentation package in broad terms includes at least one substantially cylindrical instrumentation component; a substantially cylindrical shield surrounding the instrumentation component, the shield having a diameter less than a standard predetermined diameter; and a sizing sleeve around the shield, thereby increasing the diameter of the sleeve to the standard predetermined diameter. A nuclear detector package is also disclosed that includes a substantially cylindrical crystal element; a photomultiplier tube arranged coaxially with the crystal element; an optical coupler sandwiched between one end of the crystal element and an adjacent end of the photomultiplier tube; the crystal element, optical coupler and photomultiplier tube hermetically sealed within a cylindrical shield; and a flexible support sleeve extending exteriorly along the crystal element and the photomultiplier tube and radially inside the cylindrical shield.

Abstract: A support mechanism for protecting an object is described. The support system includes at least one support or friction ring for providing dynamic protection to the object. One embodiment includes a support ring having corrugated bumps. Another embodiment includes multiple support rings axially separated by spacers. In another embodiment a support mechanism is provided having at least one friction ring in combination with O-rings. A compound optical coupler is also described, which has a self-wetting clear optical coupling gel and an elastomeric load ring.

Abstract: A safety system for mining equipment is provided having a proximity-based system with a marker field generator in an explosion-proof housing. The generator has a resonant circuit with an inductive reactance that is provided by a ferrite rod wound with an electrical conductor. Also provided is an RF receiver to receive information about the strength of the generated marker field from a sensing device used by a worker. The system provides for a personal alert device, carried by personnel to be kept at a safe distance from the mining machine, the personal alert device being capable of detecting the marker field. Also disclosed is a geosteering system that stops the cutting of a continuous miner when the cutter reaches an interface between a mineral being mined and an adjacent formation that is not to be mined.

Abstract: A rock avoidance control system for solid mineral mining using a forward looking rock/mineral interface detector and controlling the miner to cut to the detected rock/mineral interface. One or more armored gamma ray detectors are positioned near the cutter and move with the cutter such that the angular size of the field of view is not reduced. Angular movements of the cutter are measured and used for calculating the rock/mineral interface location. A device is incorporated within an armored rock detector to sense angular movements of the cutter boom and to correlate changes in gamma radiation to the angular movements, within selected energy ranges. The thickness of the remaining coal is calculated by measuring the rate at which the gamma radiation increases. In one embodiment, rock detectors are used to steer the cutting of the leading drum and/or the trailing drum a long-wall mining system.

Abstract: The invention provides, in one embodiment, a detector for a miner comprising a gamma sensing element and a light sensing element coupled to the gamma sensing element. According to the embodiment, the detector is mounted on a rotary cutter of a boring-type continuous miner such that the gamma sensing element has a view of a geologic formation being mined. A mining control system is also provided, comprising a miner having at least two rotary cutters and a gamma detector on each of the at least two rotary cutters for receiving gamma emissions from a geologic formation. The mining control system also provides an accelerometer and a rate gyro, wherein the accelerometer and the rate gyro correlate the received gamma emissions with positions of the at least two rotary cutters, and a central module that utilizes the correlated readings to determine whether the cutters should be moved.

Abstract: A rotary magnetic record disk assembly comprising a magnetic disk which is rotatably disposed within a containing jacket of material of high electrically insulating characteristics. An electrically conductive layer is disposed on the inside surface of the jacket for draining away electrostatic charge on the jacket.
