Abstract: Color temperature in a space may be adjusted by controlling lighting control devices and motorized window treatments. A position of a motorized window treatment may be controlled based on a control mode or user preference. Outside color temperature values may be limited from entering the space by closing the shade fabric of the motorized window treatment when the outside color temperature exceeds a threshold. A color temperature of outside light entering the space may be determined after the shades are adjusted. The color temperature of outside light entering the space may be determined by considering the shade fabric characteristics. The color temperature of light emitted by one or more lighting fixtures may be adjusted based on the color temperature of the light entering the space.

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: G10L19/00
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.

Filed: 2022-05-06
Abstract: Une électrode de lithium métallique comprend une couche de lithium métallique revêtant un substrat conducteur, la couche de lithium métallique n'ayant pas plus de cinq ppm d'éléments non métalliques en masse. La couche de lithium métallique est à son tour revêtue d'un polymère conformable conducteur d'ions lithium, ce qui permet d'obtenir l'électrode négative et l'électrolyte solide pour une batterie au lithium métallique rechargeable qui comprend en outre une électrode positive. Facultativement, l'électrode positive comprend du soufre élémentaire dans une matrice conductrice. L'électrode de lithium métallique revêtue de polymère conformable peut être fabriquée par un processus impliquant l'électrodéposition de lithium métallique à travers un substrat conducteur revêtu de polymère conformable, pour lequel le substrat conducteur revêtu de polymère conformable a été préparé par revêtement du substrat conducteur dans une solution du polymère conformable suivi par l'évaporation du solvant. En variante, une électrode de lithium métallique peut être directement revêtue d'un polymère conformable. Les batteries au lithium rechargeables selon des modes de réalisation de l'invention présentent une durée de vie en cyclage et une résistance à la combustion améliorées par rapport aux batteries au lithium métallique fabriquées par des procédés classiques.

Patent WO-9222230-A1 (WO)
Title: Take apart lock
Inventor: SCHENK RONALD G
IPC: A47B88/493
Filed: 1992-05-06
Abstract: A unique take-apart lock mechanism for use with drawer slides in cabinet and drawer arrangements is disclosed. The mechanism comprises a release lever (15), a butterfly catch (20) and a pair of stop blocks (26). The butterfly catch and release lever are mounted within the drawer slide (2) and the stop blocks mounted within the larger cabinet slide (1). By moving the release lever slideably within the inner channel, a pair of projetions pull outwardly biased resilient wings (21) of the butterfly catch inwardly, therefore allowing them to pass by the stop blocks, enabling the drawer to be removed from the cabinet. When the release lever is returned to its normal position, the drawer can be extended from the cabinet outwardly to a locked position thereby prohibiting it from being removed or accidentally falling.
