Abstract: Disclosed are methods, materials and devices for approximation of blood volume in a fluid. A blood indicator panel (BIP) device is provided for rapid blood volume measurement (in mls.) in a fluid (e.g., a collected surgical fluid). An RBC flocculant (e.g., polyDADMAC) may be used to induce more rapid sedimentation of red blood cells from the fluid. A series of markings is provided on one side of the BIP, each marking corresponding to a volume of blood (in milliliters). The markings are calculated by use of a formula: Vb=Vm/(Hct×1.2), wherein Hct is an average blood hematocrit, and 1.2 is an RBC packing ratio value for a conventional 1,200 ml waste collection canister (1.2 alternatively referenced as “?”). The BIP does not employ centrifugation, electronic image transmission or analysis, is temperature independent, and is accurate to about +/?10%.

Abstract: Methods and systems for acoustic sensing include determining sensing locations along a fiber to generate a beam pattern that is directed to an acoustic source.

Abstract: A transmitter sends a PPDU including a signature symbol to a receiver, where a first preset bit in the signature symbol indicates a standard version corresponding to the PPDU and/or a value of each bit in a second preset bit is 0 or 1. After the receiver receives the PPDU, if the standard version corresponding to the PPDU indicated by the first preset bit in the signature symbol in the PPDU is a standard version corresponding to a first PPDU and/or the value of each bit in the second preset bit in the signature symbol is the same as the preset value, the receiver determines that the received PPDU is the first PPDU. the transmitter and the receiver determine, by using the signature symbol in the PPDU, whether the received PPDU is the first PPDU, to identify the first PPDU, so that information in the received PPDU is correctly interpreted.

Abstract: A system for monitoring arterial pressure of a patient determines a score that is predictive of responsiveness of the patient to a therapy. Sensed hemodynamic data representative of an arterial pressure waveform of the patient are received by a hemodynamic monitor. Magnitude data and trend data are derived from the hemodynamic data. The score that is predictive of the responsiveness of the patient to the therapy is determined based on the magnitude data and the trend data of the hemodynamic parameter. A representation of the score is output.

Abstract: A front differential includes an outer ring spline mounted on an inner housing for rotation with the ring gear joinder, an inner ring spline mounted on one of the semi-axle gears, and a plurality of friction members disposed between the inner ring and the outer ring. The friction members are interleaved plates which can create a partial friction state and a fully locked state of the front differential through application of axial pressure force. The spline mounting of the inner and outer rings allows axial movement so the axial pressure force application is more accurate despite manufacturing tolerances. A ball bearing is arranged between the differential housing and the ring gear joinder. The ball bearing is connected to the differential housing by a clearance fit which allows the ball bearing to move axially relative to the differential housing.
