Abstract: Examples herein propose operating redundant ML models which have been trained using a boosting technique that considers hardware faults. The embodiments herein describe performing an evaluation process where the performance of a first ML model is measured in the presence of a hardware fault. The errors introduced by the hardware fault can then be used to train a second ML model. In one embodiment, a second evaluation process is performed where the combined performance of both the first and second trained ML models is measured in the presence of a hardware fault. The resulting errors can then be used when training a third ML model. In this manner, the three trained ML models are trained to be error aware. As a result, during operation, if a hardware fault occurs, the three ML models have better performance relative to three ML models that where not trained to be error aware.

Abstract: A neural network system includes an input layer, one or more hidden layers, and an output layer. A first layer circuit implements a first layer of the one or more hidden layers. The first layer includes a first weight space including one or more subgroups. A forward path circuit of the first layer circuit includes a multiply and accumulate circuit to receive an input from a layer preceding the first layer; and provide a first subgroup weighted sum using the input and a first plurality weights associated with a first subgroup. A scaling coefficient circuit provides a first scaling coefficient associated with the first subgroup, and applies the first scaling coefficient to the first subgroup weighted sum to generate a first subgroup scaled weighted sum. An activation circuit generates an activation based on the first subgroup scaled weighted sum and provide the activation to a layer following the first layer.

A device body, which is waterproof in one or more applications, includes a sidewall defining a receiving aperture. A crown stem includes a push button disposed within a duct of a threaded bushing and one or more O-rings disposed about the actuation stem to allow translation of the actuation stem in the duct while preventing liquids from passing through the duct. The crown stem inserts through the aperture in the case so that the threaded bushing can hermetically seal the receiving aperture when the device body is inserted into the circular receiver to prevent the liquids from entering the receiving aperture.

Abstract: Disclosed are removable “locking pins” that hold the front and rear housings of a wearable device together. These pins fit into receiving channels in the walls of the housings. Unlike screws or other fasteners, these pins do not take up space needed for internal components of the device. Unlike snaps, the pins are usable with housings that are very rigid (e.g., metal or ceramic). In some embodiments, the pins are entirely hidden from view, and thus they do not detract from the appearance of the device. Also in some embodiments, the pins fit entirely outside of a water seal for the device, thus reducing cost and assembly complexity.
