Abstract: A multi-purpose tile is installable on ceilings walls and floors. The tile includes a base layer of foam plastic material bonded to an upper substrate layer of non-foam plastic or metal material. The bonding process includes pressurization of the foam layer to the non-foam constituents of the tile. The pressure is at a selected level that basically does not change the density of the foam base layer before and after pressurization. The thickness ratio of the foam based layer relati ve to other constituent layers of the tile can be approximately 15 to 20 times thicker than the other constituent layers thus ensuring that the tile is a lightweight, low density structure that is easy to handle and install.

Title: Method and apparatus for generating from a coefficient domain representation of hoa signals a mixed spatial/coefficient domain representation of said hoa signals
Inventor: KORDON SVEN
IPC: G10L19/008
Filed: 2014-06-24
Abstract: There are two representations for Higher Order Ambisonics denoted HOA: spatial domain and coefficient domain. The invention generates from a coefficient domain representation a mixed spatial/coefficient domain representation, wherein the number of said HOA signals can be variable. A vector of coefficient domain signals is separated into a vector of coefficient domain signals having a constant number of HOA coefficients and a vector of coefficient domain signals having a variable number of HOA coefficients. The constant-number HOA coefficients vector is transformed to a corresponding spatial domain signal vector. In order to facilitate high- quality coding, without creating signal discontinuities the variable-number HOA coefficients vector of coefficient domain signals is adaptively normalised and multiplexed with the vector of spatial domain signals.

Abstract: In a vehicular parking lock device, the parking lock is actuated when a line pressure is supplied to the left end of a hydraulic pressure actuator (25) through a second solenoid valve (32A) or when the hydraulic pressure of an accumulator (37, 38) is supplied to the left end of the hydraulic pressure actuator (25) through a third solenoid valve (32B). The parking lock is released when a line pressure is supplied to the right end of the hydraulic pressure actuator (25) through a first solenoid valve (32C, 32D). The second solenoid valve (32A) and the first solenoid valve (32D) also serve as a solenoid valve for supplying a hydraulic pressure to a torque converter (40) and as a solenoid valve for supplying hydraulic pressure to a hydraulic pressure brake (41) used for transmission, respectively. This makes it possible to reduce the total number of solenoid valves and thereby reduce the parts count of a hydraulic circuit (31).
