Abstract: Methods and systems are provided for communication between a wireless charging station and an electric vehicle to facilitate wireless power transfer from the charging station to the vehicle. The vehicle comprises a near-field proximity transmitter circuit for transmitting a proximity signal to a near-field proximity receiver circuit on the charging station. While the received proximity signal is indicative of the vehicle being insufficiently proximate to the charging station for efficient power transfer, the charging station outputs instructions to move the vehicle towards the charging station. When the received proximity signal at the charging station is indicative of the vehicle being sufficiently proximate to the charging station, the charging station may transmit wireless power to a wireless power receiver on vehicle.

Abstract: Apparatuses, systems, and methods in which reflective slats are configured to redirect light received from various sun positions are provided. The slats or mirrored array could be coupled to a base of the redirector, such that an adjustment of an angle of the base relative to the horizontal adjusts an angle of each slat relative to the horizontal. In some aspects, an algorithm can be used to determine the angle of tilt that maximizes the transmission efficiency for the mirror array.

Abstract: Tourniquet apparatus for rapidly and accurately measuring a patient's limb occlusion pressure comprises: an inflatable tourniquet cuff for encircling a limb at a location; a tourniquet instrument releasably connectable to the cuff that includes: pressure sensing means for producing a cuff pressure signal indicative of the level of pressure in the cuff; pressure regulation means communicating with the cuff and responsive to the cuff pressure signal for regulating the pressure in the cuff near a reference pressure level; blood flow transducing means adapted for applying to a portion of the limb distal to the cuff to produce a blood flow signal indicative of blood flow in the portion; and limb occlusion pressure means responsive to the blood flow signal and the cuff pressure signal and operable for detecting arterial pulsations of blood flow, for increasing the reference pressure level in synchrony with the arterial pulsations and for producing a limb occlusion pressure value indicative of the lowest cuff pressu

Abstract: A low-cost contour cuff for surgical tourniquet systems comprises: a sheath containing an inflatable bladder, the sheath having an arcuate shape, an outer surface and a centerline equidistant between first and second side edges; a securing strap non-releasably attached to the outer surface and formed of substantially inextensible material having a shape that is predetermined and substantially flat, wherein the strap includes a bending portion near a first strap end and a fastening portion near a second strap end, and wherein the bending portion is adapted to allow twisting of the bending portion out of the substantially flat shape to facilitate positioning of the fastening portion into any of a plurality of positions in the substantially flat shape; and fastening means for releasably attaching the fastening portion of the securing strap to the outer surface whenever the sheath is curved into a position for surrounding a limb.

Abstract: Low-cost tourniquet cuff apparatus includes: an inflatable bladder formed of flexible material having a bladder width dimension when the bladder is uninflated and a having a bladder length dimension sufficient for encircling a limb of a surgical patient at a desired location on the limb and for overlapping upon itself, wherein the bladder includes a bladder first inner surface facing a bladder second inner surface along the bladder length dimension and across the bladder width dimension when the bladder is uninflated; securing means for securing the overlapping bladder around the limb at the desired location; port means communicating pneumatically with the inflatable bladder and releasably connectable to a tourniquet instrument for supplying the bladder with pressurized gas; and stiffener means having a predetermined stiffness and having a stiffener width dimension less than the bladder width dimension, wherein the stiffener means is non-releasably attached to the bladder first inner surface within the inflat

Abstract: A low-cost disposable tourniquet cuff includes: a first sheet formed of flexible material that is impermeable to gas; a second sheet facing the first sheet and formed of flexible material impermeable to gas; a bladder seal joining the first sheet to the second sheet around a perimeter to form an inflatable bladder within the perimeter; port means communicating pneumatically with the bladder and releasably connectable to a tourniquet instrument; stiffener means contained within the inflatable bladder and formed of gas-impermeable material less flexible than the first sheet, wherein the stiffener means has a stiffener width dimension less than the bladder width dimension and is joined to the first sheet to form a non-inflatable portion of the first sheet; and securing means attached to the non-inflatable portion of the first sheet and adapted to allow a surgical user to releasably secure the cuff around the limb at the desired location so that the bladder overlaps upon itself.
