Abstract: Techniques for utilizing excess heat generated by an oven to generate electricity are provided. In one example, an oven can comprise a coolant pathway positioned adjacent to a hollow space within the oven, wherein the hollow space can contain heat. The oven can also comprise a chamber in fluid communication with the coolant pathway. The oven can further comprise a turbine in fluid communication with the chamber and an outlet. Moreover, the oven can comprise a generator connected to the turbine, wherein rotation of the turbine can power the generator.

Abstract: An attachment handle for an exercise machine includes a flexible tension member, a first ring secured to a first end of the flexible tension member, a second ring secured to a second end of the flexible tension member, and a hand grip having a bore surrounding the flexible tension member. The hand grip is slideable along the flexible tension member between the first and second rings. The hand grip defines a first shoulder at a first end of the hand grip and a second shoulder at a second end of the hand grip.

Abstract: An unmanned vehicle including a vehicle body, a propulsion system, a maneuvering system, a vehicle control system, a buoyancy control system, a sensor system, and at least one power supply is disclosed. The propulsion system, maneuvering system, vehicle control system, buoyancy control system, sensor system, and power supply are carried by the vehicle body. The sensor system includes a sensor adapted to detect an item of interest and provide an item of interest signal to the vehicle control system. The vehicle control system is adapted to receive the item of interest signal, identify an item of interest classification and provide a classification signal. The classification signal is determined by the item of interest classification and is utilized by the propulsion system, maneuvering system, vehicle control system, or buoyancy control system to avoid physical, electrical, acoustic, or thermal detection of the unmanned vehicle by the item of interest.

Abstract: An exercise bar includes a center bar; a pair of weight bars, each weight bar rotatable relative to the center bar about a pivot axis to a plurality of camber positions; a pair of support bars configured to rest on a user's shoulder, each support bar extending from one of the weight bars; and a locking mechanism for locking the weight bars in any of the plurality of camber positions.

Abstract: A radio-based position location system for determining a relative position of a first object with respect to a second object may include a first radio operatively associated with the first object. A first directional antenna having at least a high gain region is mounted to the second object so that the high gain region is directed generally outwardly from the second object and defines a first detection zone. A second directional antenna having at least a high gain region is also mounted to the second object and is oriented so that the high gain region is also directed generally outwardly and defines a second detection zone. A second radio connected to the first and second directional antennas exchanges radio signals with at least the first radio to determine the relative position of the first object with respect to the second object at least in part by determining a time-of-flight of a radio signal.

Abstract: Methods and apparatus for locating and tracking objects in a mining environment are disclosed that include selecting an operational area within which the locations of a plurality of objects are to be determined and tracked over time. Radio transceiver systems and associated display systems provided to the plurality objects are operated to form an ad-hoc, peer-to-peer network. The relative positions of the various objects are determined by measuring the time-of-flight of radio signals exchanged between various ones of the radio transceiver systems and analyzing the time-of-flight of such exchanged radio signals. The relative positions of at least some of the objects within the operational area are then displayed on the display system.
