Abstract:
A novel balance exercise apparatus and method of training is disclosed which includes a spanning system which spans between two positions in space and supports a suspended system which is suspended between the two positions in space. A user trains their balance skills and exercises by positioning all or part of their body on the suspended system and then moves their body to maintain their balance while remaining in place or doing exercises. The suspended system creates a dynamic balance environment where the suspended system may move such as swing, bend, rotate, or twist, all controlled by the balance and movement of the user. The suspended system may consist of rigid and/or flexible devices that are supported by the spanning system above the ground. In addition, the spanning system and the suspended system may include devices to vary the nature and difficulty of the dynamic balance environment. The dynamic balance environment may range from stiff to very soft and incorporate variable spring and bounce properties. The dynamic nature of the balance environment makes this system a very effective and challenging balance training system.
Abstract:
A system and method for transferring power using a data communications signal line. The data communications signal line is in a high impedance powerless state when idle. A main device is electrically coupled to the data communications signal line. The main device generates and transmits a signal on the data communications signal line. The signal includes power generation and non-power generation characters. A peripheral device is electrically coupled to the data communications signal line. The peripheral device has a functional unit arranged to perform a desired function for the peripheral device. A power conversion module is electrically coupled to the data communications signal line and receives the signal. The power conversion module converts power from the received signal to a form suitable for storage. A controller is in electrical communication with the functional unit and the power conversion module. The controller receives the power generation and non-power generation characters, strips the power generation characters from the signal and transmits the non-power generation characters to the functional unit.

Abstract:
A suture needle construct and method for extracapsular ligament reconstruction in mammals. The joint is first is first explored, and the damaged ligament and meniscus are debrided. The joint capsule is closed and a tunnel is created at the appropriate location in the proximal tibia for tibial fixation. Subsequent to the formation of the tibial tunnel, a suture having a substantially curved needle at one end and a substantially straight needle at the other end is brought in the proximity of the joint. The suture is passed around the lateral fabella using the substantially curved needle, then deep to the patellar ligament using the substantially straight needle, and through the tibial tunnel using the straight needle. The needles are cut off, and the sutures are tensioned over repair site.
Abstract:
Gallium nitride material transistors and methods associated with the same are provided. The transistors may be used in power applications by amplifying an input signal to produce an output signal having increased power. The transistors may be designed to transmit the majority of the output signal within a specific transmission channel (defined in terms of frequency), while minimizing transmission in adjacent channels. This ability gives the transistors excellent linearity which results in high signal quality and limits errors in transmitted data. The transistors may be designed to achieve low ACPR values (a measure of excellent linearity), while still operating at high drain efficiencies and/or high output powers. Such properties enable the transistors to be used in RF power applications including third generation (3G) power applications based on W-CDMA modulation.
Abstract:
The scintillating screen of digital imaging systems used in conventional transmission electron microscopy is discretized and the scintillating material is contained in a cellular structure having a geometry judiciously selected for coupling to the optical channels of the imaging system. This allows optical matching, without smearing, between the elements of the scintillating screen and the discrete light-collecting and light-registering optical channels of the system. Cross-talk among optical channels is consequently minimized and the resulting light-imaging resolution of the digital imaging system is optimized.

A plurality of electronic controlling components for controlling the torque sensor, wherein the electronic controlling components are configured upon another substrate in association with an antenna for sending and receiving the wireless signals to and from the torque sensor, such that the torque sensor is located on a rotating member in order to generate signals indicative of a torque associated with the rotating member, and wherein the signals are wirelessly transmittable from the torque the via the antenna configured upon the substrate in association with the torque sensor.
Abstract:
A switch-type power converter comprising an FET switch operating in a variable duty cycle mode under the control of a Unitrode 3846 integrated circuit controller. Indications of excess input voltage and reverse battery connections are provided by circuits including an element which permanently changes state. A cooling fan mounted on a finned heat sink is operated in a variable speed mode. A single thermistor sensor provides inputs to both the fan speed control and a thermal shutdown circuit connected to shut down the gate drives to the FET switch in the event of a high temperature condition. Another shutdown function is provided in response to an input overvoltage condition by way of an operational amplifier. The converter uses foldback for short circuit protection and is compatible with microprocessor units to selectively provide multiple output voltage levels.
