Abstract: A refrigerator includes a filter, a receiver, a manifold, and a cam. The filter has a handle extending therefrom. The receiver defines a cavity configured to receive the filter. The manifold is configured to engage an opposing end of the filter relative to the handle via axial rotation of the filter. The manifold is configured to pivot upward to transition the filter to an activated position. The manifold is configured to pivot downward to transition the filter to a deactivated position. The cam is configured to interfere with the handle in response to partial axial rotation of the filter to prevent the filter from pivoting upward to the activated position. The cam is configured to provide clearance for the handle in response to full axial rotation of the filter to facilitate the filter pivoting upward to the activated position.

Abstract: This relates to methods and apparatus for estimating an object profile to improve accuracy of touch sensor panel input (e.g., reducing input position wobble for a stylus or finger translating on a surface over and between electrodes of a touch sensor panel). In some examples, the object profile estimation can begin with an initial profile estimate that can allow the object profile estimation to converge for a large range of possible input object sizes, shapes, distances, and/or orientations. The object profile information can use data from multiple frames of data acquisition as well as multiple pixels in the panel to construct the object profile estimate based on the input measurement. Specifically, the object profile can be estimated by measuring the object at various positions relative to touch pixels or nodes and gaps between touch pixels or nodes over multiple frames of sensor data and combining the measurement data of the multiple frames.

Abstract: A dual retention apparatus comprises: a locking pin; a pin retaining device, the pin slidable therein, comprising: a starting pin position; a pin locking mechanism; a partial pin locking mechanism; a pin path from the starting pin position to the pin locking mechanism, the partial pin locking mechanism located on the pin path and configured to prevent the pin from sliding back towards the starting pin position and allowing the pin to slide towards the pin locking mechanism, the pin locking mechanism configured to lock the pin therein; and a pin return path from the pin locking mechanism to the starting position, the pin return path bypassing the partial pin locking mechanism; and, a biasing device configured to relatively bias the pin along at least a portion of the pin path towards the pin locking mechanism, and further bias the pin into the pin locking mechanism.
