Abstract:
A device for converting joystick controller generated analog and digital signals into Universal Serial Bus (USB) format, or for converting imported pulse position modulated (PPM) encoded signals from an external radio control (RC) transmitter into USB format data. The device is used, in an embodiment, for controlling simulated RC model aircraft as displayed, for example on a personal computer screen through the use of computer software. In an embodiment, the device includes a pair of two-axis gimbals, an auxiliary channel control potentiometer, and various control key switches to generate analog and digital joystick type signals as a result of direct manipulation by a user. The device also includes microcontroller circuitry for importing PPM signals, such as PPM signals generated by a commercially available model aircraft RC transmitter, to a USB port signal for interface with a computer.
Abstract:
An apparatus is disclosed comprising a first attachment portion fixed to a housing and a detachable match strike device comprised of a first surface having a second attachment portion and a second surface, opposite the first surface, having a match strike material. The first attachment portion may be VELCRO (Trademarked) or a VELCRO (Trademarked) portion comprised of either “hooks” or “loops”. The second attachment portion may be comprised of a VELCRO (Trademarked) portion which attaches to the first attachment portion. The first attachment portion attaches to the second attachment portion to connect the detachable match strike device to the housing. The first attachment and the second attachment portions may be strips of VELCRO (Trademarked) material. The housing may be a matchbox. The housing may be a circular receptacle, and the first attachment portion and the second attachment portions may be circular. The detachable match strike device may be comprised of a backing material to which the second attachment portion and the match strike material are fixed.
Abstract:
Improved barstar DNAs, such as synthetic barstar DNAs, produce high amounts of barstar protein in eucaryotic cells, particularly in plant cells, and especially in stamen cells such as tapetum cells. Synthetic barstar DNAs have less than 40% A and T nucleotides. Other improved barstar DNAs encode improved barstar proteins which have an N-terminus which starts with Met-Xaa wherein Xaa is Alanine, Valine, Glycine, Aspartic acid or Glutamic acid. Plan cells and plants contain the improved barstar DNAs and/or express the improved barstar protein.
Abstract:
An I/O interface, compatible with industry standards, for interfacing a host to a peripheral device. The interface includes a clock signal, a bus, an address latch enable signal, a peripheral device ready signal, a command signal, a device selected backoff signal, and a reset signal, resulting in an I/O interface capable of ISA-compatible operation with only 22 pins. Address, data, command, interrupt request, and DMA request information are communicated between the host and the peripheral device via a single bus by multiplexing the information on the bus using phasing techniques.
Abstract:
A system for enhancing the effect of stereo audio signals while maintaining the central audio image includes an expander circuit that tracks the monaural information that is common to both left and right channels and that uses such monaural information to control variable attenuators that influence the inputs to the left and right audio image placement filters.
Abstract:
In exercise apparatus for underwater use including an apparatus frame, and movable members mounted on the frame to be moved by a user of the apparatus, flap members, e.g., flat plates, are mounted on the movable members for movement therewith within the surrounding water. The water resists movement of the flap means, hence provides resistance to movement of the members moved by the user. Disclosed are apparatus which, in use, simulate the movements of a cross-country skier, an ice-skating speed racer, and a rower of a row boat. Arrangements are also disclosed for selectively varying the resistance to movement provided by the flap members in response to the direction of movement of the movable members. All exercises with equipment embodying the invention can be performed with all of the user's body and limbs being submerged in water in order to decrease strains on the user's joints, thereby providing an exercise mechanism which incorporates high resistance to the user's muscles with low impact on the user's joints.
Abstract:
A linear stacked stage suitable for REBL may include a first upper fast stage configured to translate a first plurality of wafers in a first direction along a first axis, the first upper fast stage configured to secure a first plurality of wafers; a second upper fast stage configured to translate a second plurality of wafers in a second direction along the first axis, the second upper fast stage configured to secure the second plurality of wafers, the second direction opposite to the first direction, wherein the translation of the first upper fast stage and the translation of the second upper fast stage are configured to substantially eliminate inertial reaction forces generated by motion of the first upper fast stage and the second upper fast stage; and a carrier stage configured to translate the first and second upper fast stages along a second axis.
Abstract:
An assembly comprises a framework, which is intended to be located on the front face of a motor vehicle, and a bracket. The assembly includes a device for positioning the bracket on the framework and the bracket includes a securing device for supporting an actuator that is capable of driving one or more members to be mounted onto the framework.
Abstract:
A method is disclosed that generates design profiles and a surface therefrom that promote water drainage from soil in an area of interest. Topographical data describing an initial surface of the area of interest are used to form initial profiles. The method generates the design profiles using the initial profiles and desired design parameters such as minimum slope, maximum slope, optimal slope, maximum depth, optimal depth, starting elevation, ending elevation, rules of curvature, and rules of earth balancing. The method generates design surface profiles so that the cut volumes and fill volumes of the soil are at or near balance as much as possible from the available soil in the area of interest.
