Abstract: A method for processing biological tissue used in biological prostheses includes providing a tissue procurement solution formed from a phosphate buffered saline (PBS) solution and a chelating agent. The tissue is transferred from the tissue procurement solution and undergoes chemical fixation. The fixed tissue is then immersed in a series of fresh bioburden reduction process (BRP) solutions to extract phospholipids. The tissue procurement solution reduces the bioburden on the stored tissue and preserves tissue architecture by minimizing tissue swelling. The tissue procurement solution further reduces calcium from the incoming water and/or tissue, and inhibits enzymes that digest the collagen matrix. The serial immersion of the tissue in the fresh bioburden solutions ensures optimal extraction of phospholipids thereby mitigating subsequent calcification of the tissue.

Abstract: A digit rate reducing system for PCM signals comprises a predictor stage, an automatic gain control stage, and a quantizer stage for adaptive quantizing. The predictor stage includes a predictor and a subtractor for subtracting from a sample xn of the PCM input signal a predicted signal xpn derived from preceding samples. The subtractor provides a difference signal dn representing prediction error to the automatic gain control (AGC) stage. A divider in the AGC stage divides the difference signal dn by m, providing a divided signal en to the quantizer stage. In this last stage, a quantizer encodes the divided signal en into a signal Yn of reduced rate. The predictor uses a first adder which receives the predicted signal xpn and a reconstituted signal dn derived from the reduced rate signal Yn; a plurality of shift registers and associated multipliers; and a second adder connected to the outputs of the multiplier. Shift registers T1 . . . TN are coupled to the output of the first adder, and provide a series of delayed signals to multipliers M1 . . . MN for multiplying by respective coefficients ai (n) derived from the preceding samples. At least one of the predictor coefficients ai (n) is applied to the quantizer, whereby the type of coding is adapted to the statistical properties (ie, the conditional probability distribution curve) of the PCM input signal.

Abstract: Arrangement in data transmission between a transmitting computer, sending signal words containing start-stop information, message words and address-control signal information, and a receiving computer, for providing separate supervision of faults on the transmission lines and of such errors which are caused by faults in the signal equipment pertaining to the computer of the transmitter side, intermediate stations or the computer on the receiver side. The arrangement comprises means for generating and checking two check sums which are mutually supplementary, an inner check sum (S) for monitoring the hardware incorporated in computers and intermediate stations on a transmission path, and an outer check sum (YS) for monitoring the transmission lines. A check sum generating circuit is associated with the transmitting computer, and contains an adding circuit and a register which, by adding all the message words in a complete signal word, generates the inner check sum (S). An outer check sum generating circuit generates the outer check sum (YS by adding the address - control signal information, message words and the inner check sum. The correctness of the respective signal sum is checked in possible intermediate stations by reestablishing the sums in adding circuits and by comparison in comparator circuits between the respective reestablished sum and the corresponding check sum coming from the line. In the intermediate station there is furthermore generated, with the aid of an adder and a register, a new outer check sum on the basis of changed address-control signal information. The correctness of the respective check sum is also checked in the receiving computer by reestablishing the sums in adding circuits and by comparison in comparator circuits between the respective reestablished sum and the corresponding check sum coming from the line. In every terminal where the sums are checked and compared there is the possibility of transmitting control signals in response to the comparison results, which signals initiate retransmission of the message or switching to another line.

Abstract: An electronic arrangement for determination of reactive power, including two transducers delivering at their outputs measuring voltages proportional to supply current and supply voltage. An additional phase shift of 90 DEG  between the two measuring voltages is produced by phase-shifting elements. A signal proportional to reactive power is produced in a following multiplier element.

Abstract: An apparatus and a method are provided for detecting discontinuities in a sequence of time code addresses recorded on a tape, such as a video tape, which also has control pulses recorded serially along its length to synchronize the motion of the tape relative to transducer heads which read and write information signals on the tape. The apparatus and method of this invention read the current time code address from the tape, count the control pulses read as the tape moves, establish a known relationship between the current time code address and the count of control pulses, so that the count represents a counted tape address, and compare the current time code address with the counted tape address for producing a non-compare signal in the event of a difference between these two compared values. A time code discontinuity signal is generated when a predetermined number of successive comparisons result in non-compare signals, indicating that the time code addresses read from the tape have not varied sequentially in a uniform relation to the control pulses. The value of the current time code address and the counted tape address at the time a discontinuity is detected can be used to define both the location and the magnitude of the discontinuity or to enable accurate calculation of the distance between two time code addresses each located on an opposite side of such a discontinuity.
