Abstract: A self-releasing clutch assembly for locking a vehicle door lock. The clutch assembly (11) includes a servo-actuated input drive and a cinching output drive. A gear shaped first actuator (42) is mounted to the input drive. A cylindrical second actuator (44) is mounted to the output drive and is moveable relative to the first actuator. Four pairs of rollers (50) are interdisposed between the first and second actuators and moveable between a disengaged position and an engaged position. With the disengaged position, the rollers rest against the first actuator and allowing the second actuator to rotate relative thereto. With the engaged position, the rollers interlock the first and second actuators for relative concurrent movement. The clutch assembly is characterized by the first actuator including four driving surfaces (43) and the second actuator including four corresponding abutments (48). The driving surfaces engage and move the rollers from the disengaged position to the engaged position in response to movement by the input drive. The abutments then lock the rollers between the first and second actuators to couple the input drive with the output drive thereby transferring the movement of the input drive to the output drive. The subject invention also includes a biasing device (54) for automatically returning the rollers to the disengaged position when the driving force from the first actuator ceases.

Abstract: The invention disclosed provides a method for inducing nucleation in a polymer by subjecting the polymer containing dissolved gas to an external stress generated, for example, by applying hydrostatic or mechanical pressure. The applied stress restricts the bubble growth so that the foamed materials have small cells and high cell density. Such microcellular foams can be produced over a wide low temperature range, i.e. from the temperature at which the polymer is conditioned with the blowing agent up to about the glass transition temperature of the polymer-blowing agent system. Stress induced nucleation can also be conducted at higher temperatures i.e. up to about the Tg of the neat polymer, leading to foams with larger cells. A variety of homogeneous and heterogeneous foams can be produced by this technique.

Abstract: A battery sheath made of formed and cold-rolled sheet metal as well as a process for manufacturing the battery sheath are proposed. In the process, cold-rolled strip stock is provided on at least one side with a coating of Ni, Co, Fe, Sn, In, Pd, Bi or their alloys in an electroplating bath, e.g., a Watts-type bath. As an additional component, the electroplating bath contains electrically conductive particles such as carbon, carbon black, graphite, TiS2, TaS2, MoSi2. These particles are deposited on the base material during electroplating together with Ni, Co, Fe, Sn, In, Pd, Bi or their alloys. The sheet metal side with, for example, the carbon-containing electroplated coating faces preferably inwardly when the sheet is formed into a battery sheath. Batteries with battery sheaths produced in this manner exhibit reduced increase in internal resistance, even with prolonged storage, as compared to known batteries.

Abstract: A method for reducing a propagation delay of a digital filter. The digital filter has an input path and an output path and includes a set of delay elements and a number of taps. The taps couples the input path to the output path. Each of the taps includes a coefficient, a multiplier and an adder. Each of the delay elements is disposed between two adjacent taps. The delay elements are placed in both the input path and the output path of the digital filter, such that the digital filter has fewer delay elements in the input path than a direct-form digital filter having the same number of taps in a direct-form structure and has fewer delay elements in the output path than a transposed-form digital filter having the same number of taps in a transposed-form structure, and such that the digital filter has same transfer function as the direct-form digital filter and the transposed-form digital filter.

Abstract: A method is provided for the quantization of a coefficient. The method comprises: supplying a coefficient K; supplying a quantization parameter (QP); forming a quantization value (L) from the coefficient K using a mantissa portion (Am(QP)) and an exponential portion (x Ac(QP) ). Typically, the value of x is 2. In some aspects of the method, forming a quantization value (L) from the coefficient K included L = K* A(QP) = K* Am(QP)*(2 Ac(QP) ). In other aspects, the method further comprises: normalizing the quantization value by 2 N  as follows: Ln = L/2 N  = K*Am(QP)/2 (N-Ac(QP) ). In some aspects, forming a quantization value includes forming a set of recursive quantization factors with a period P, where A(QP+P)=A(QP)/x. Forming recursive quantization factors includes forming recursive mantissa factors, where Am(QP)=Am(QP mod P), and forming recursive exponential factors, where Ae(QP) = Ae(QP mod P) - QP/P.
