Abstract: An inflatable mattress for use on a truck bed is disclosed and claimed. The inflatable mattress includes a lower mattress layer with left and right recessions dimensioned to substantially surround the wheel well sides. The inflatable mattress includes an upper mattress layer dimensioned to substantially cover the lower mattress layer and the wheel well tops.

Abstract: A blow gun includes a hollow ammunition chamber having an internal volume that is large enough to hold at least 30 spherical projectiles, for example plastic BBs. The ammunition chamber has a breath receiving orifice, and a firing port. A barrel obtrudes from the hollow ammunition chamber through the firing port. The barrel has a cylindrical bore therethrough, that defines an internal diameter that is greater than the spherical projectile diameter but no greater than 1.7 times the spherical projectile diameter. The barrel has an outer surface that is in sliding contact with the firing port. The barrel may have a storage position in which most of the barrel is disposed within the internal volume of the hollow ammunition chamber, and a firing position in which most of the barrel is disposed outside of the hollow ammunition chamber.

Abstract: A receiver employs low-rate processing to synthesize the effect of high-rate interference in a received multi-rate signal. Each high-rate subchannel is analyzed on its low-rate descendents to produce symbol estimates for each low-rate symbol interval. The symbol estimates are applied to low-rate descendent subchannels, which are then combined to synthesize the effects of the high-rate interference. An interference canceller processes the synthesized interference with the received signal for producing an interference-cancelled signal. Alternatively, analogous steps may be applied at high-rate to analyze, synthesize, and cancel the effects of low-rate interference in a multi-rate signal.

Abstract: A receiver is configured for canceling intra-cell and inter-cell interference in coded, multiple-access, spread-spectrum transmissions that propagate through frequency-selective communication channels. The receiver employs iterative symbol-estimate weighting, subtractive cancellation with a stabilizing step-size, and mixed-decision symbol estimates. Receiver embodiments may be implemented explicitly in software or programmed hardware, or implicitly in standard Rake-based hardware either within the Rake (i.e., at the finger level) or outside the Rake (i.e., at the user or subchannel symbol level).

Abstract: An apparatus and method to suppress vacuum surges in a surgical aspiration system is disclosed and claimed. A vacuum surge suppressor includes a first fluid path for coupling to a surgical instrument, and a filter attached to the first fluid path. A flow restrictor is coupled to the filter with the filter disposed upstream of the flow restrictor. The vacuum surge suppressor also includes a second fluid path for coupling to a vacuum pump. The second fluid path is connected to the flow restrictor and disposed downstream of the flow restrictor. The second fluid path defines a path internal pressure. A third fluid path is coupled to the filter and is connected to the second fluid path, bypassing the flow restrictor. A valve in the third fluid path obstructs flow in the third fluid path in response to the path internal pressure.

Abstract: Interference is cancelled from a baseband signal by synthesizing interference from estimated symbols in interfering subchannels. The estimated symbols are hard-coded, soft weighted, or zeroed, depending on the value of an estimated pre-processed signal-to-interference-and-noise ratio (SINR) in each subchannel in order to maximize a post-processed SINR. The estimated pre-processed SINR is obtained from averages of estimated symbol energies and estimated noise variances, or from related statistical procedures.

Abstract: A medicine vaporizer for an inhaler includes a metal louver. The metal louver has a first end and an opposing second end, and defines a louver thickness. The medicine vaporizer also includes first and second electrically conductive pins that define a pin thickness greater than the louver thickness. The first electrically conductive pin includes a first crimping region that is attached to and crimped over the first end. The second electrically conductive pin includes a second crimping region that is attached to and crimped over the second end.

Abstract: This invention teaches to the details of an interference canceling receiver for canceling intra-cell and inter-cell interference in coded, multiple-access, spread spectrum transmissions that propagate through frequency selective communication channels to a multiplicity of receive antennas. The receiver is designed or adapted through the repeated use of symbol-estimate weighting, subtractive cancellation with a stabilizing step-size, and mixed-decision symbol estimates. Receiver embodiments may be designed, adapted, and implemented explicitly in software or programmed hardware, or implicitly in standard RAKE-based hardware either within the RAKE (i.e., at the finger level) or outside the RAKE (i.e., at the user or subchannel symbol level). Embodiments may be employed in user equipment on the forward link or in a base station on the reverse link. It may be adapted to general signal processing applications where a signal is to be extracted from interference.

Abstract: A CORDIC processor is configured to perform orthogonal or oblique CORDIC projections in order to cancel interference in a received signal. The CORDIC projection can be used to rotate an interference signal vector so that its only non-zero component is in the last Euclidean coordinate of the representative vector. A measurement vector is then subject to the same rotations as the interference vector. As a result of the rotation on the measurement vector, all components of the measurement vector parallel to the interference vector will be resolved onto the same coordinate as the rotated interference vector. The parallel components of the symbol vector can be cancelled by zeroing that coordinate, and the modified measurement vector can then be rotated back to its original coordinates, to produce an orthogonally projected version of the original measurement vector. Typically, the projection is onto a subspace that is orthogonal or oblique to an interference subspace, which may be one-dimensional.
