Abstract: A lifting harness for assisting a worker to transfer a load is provided, the lifting harness comprising: a belt; a pair of lifting pads slidably mounted on the belt; a back including a pair of arms attached to the belt, the pair of arms converging towards a distal end; a loop proximate to the distal end; and a mobile lifting strap, the mobile lifting strap including a strap first distal end, a strap second distal end and a length therebetween, the length slidably extending through the loop; a first lifting loop proximate to the strap first distal end; and a second lifting loop proximate to the strap second distal end.

Abstract: Provided is a portable, thermoelectrically powered device in form of a modified vessel and attachments, for extracting electricity from the temperature differential of liquids, slurries, and solids, and that of ambient air. The device utilizes two container surfaces with a temperature differential between them, and at least one thermoelectric generator in electrical communication with circuitry comprising at least one step up DC-DC voltage converter. In a preferred embodiment, the device includes a second DC-DC voltage converter and a storage battery to provide electrical power at a selected voltage to external personal devices such as cell phones, iPods, flashlights, and tablets for recharging or operation of those external devices.

Abstract: Disclosed herein are embodiments of novel WPT systems, devices, and methods of using the same. Also disclosed herein are methods for controlling the power delivered from a stationary source (e.g., a primary coil) to a moving telemetric device (e.g., a secondary coil) via magnetic resonance coupling. The systems, device, and methods described herein can be used to tune and/or detune resonant frequency between a primary coil and a telemetric device so as to prevent device malfunction and/or tissue damage for the small animals associated with the telemetric device.

Abstract: Provided is a portable, thermoelectrically powered device, such as a flashlight or headlamp. The device comprises at least one thermoelectric generator for extracting body heat from a user, the Thermoelectric generator located on and extending through an elongated open ended outer shell, a heat sink in contact with an inner surface of the thermoelectric generator and configured to provide an elongated first cooling channel therethrough, circuitry in electrical communication with the thermoelectric generator, the circuitry comprising a transistor oscillator, a step-up transformer and a decoupling capacitor, the circuitry in electrical communication with a power sink, such that in use, a temperature gradient across the thermoelectric generator is sufficient to result in generation of at least about 25 ?W of power.

Abstract: Dolorimeters and methods of use thereof are provided. The dolorimeters comprise an integral apparatus having sensor means having a property which varies according to pressure or force applied to the means and a reporter means. The dolorimeter can be worn on a finger or thumb of a practitioner and allows for quantification of pressure or force applied to a patient. The reporter may send an audible, light or radio signal. The dolorimeter is further provided with means for calibration and an initiator to initiate calibration.

Abstract: This invention pertains to a novel reverse thread carpule dental safety syringe which is useful to dentists in freezing the gums of their patients prior to performing dental work on the patients' teeth, and subsequently retracting the needle into the carpule. A dental syringe for use with a carpule comprising: (a) a hollow barrel; (b) a handle and plunger adapted to reciprocate within the barrel, the end of the plunger removed from the handle being adapted to releasably engage with a first end of a carpule; (c) a carpule receiving cavity at one end of the barrel in alignment with the plunger; and (d) an engagement member at the end of the barrel opposite the handle and plunger for releasably engaging a second end of a carpule.
