Abstract: Wearable devices protect against musculoskeletal injuries and enhance performance. Systems and methods provide wearable devices to assist with human motion during physical activities, such as performing movements (e.g., lifting) and holding static poses (e.g., crouching, or holding a tool while working overhead). Materials, constructions, and system architectures allow the wearable devices to be worn over, under, or integrated into clothing for extended periods of time to improve performance or reduce risk of injury. Sensors may be included in the wearable devices to detect various activities, motions, and postures of the wearer, and various active and semi-active controls approaches may leverage sensor information to provide tailored assistance to individual users. Various controls optimization techniques ensure the wearable devices operate at peak efficiency.

Abstract: A method of manufacturing a casing of an electronic device including the following steps is provided. A metallic housing is provided, wherein the metallic housing has an inner surface and an outer surface opposite to the inner surface and includes a back region and at least one side region. At least one gap, a plurality of apertures and a non-conductive layer are formed on the inner surface of the metallic housing, wherein the apertures is formed on a surface of the at least one gap, part of the non-conductive layer is formed in the at least one gap and extended from the back region to the at least one side region, and part of the non-conductive layer is extended into the apertures. Part of the metallic housing is removed for exposing part of the non-conductive layer, thereby forming a plurality of non-conductive spacers located in the at least one gap.

Abstract: A metallic housing of an electronic device including an inner surface, an outer surface and a first non-conductive spacer is provided. The outer surface is opposite to the inner surface, and the outer surface has a back side and lateral sides connecting with the back side. The inner surface is substantially a recessed structure. The metallic housing having a first gap and a second gap substantially located at two opposite ends of the metallic housing and being parallel with each other. The first gap and the second gap each communicates the inner surface and the outer surface. The first non-conductive spacer is disposed the first gap of the metallic housing.

Abstract: A lot of space and material is typically used to have a full range of exercise weights. An adjustable exercise weight is herein provided to save space and material. The exercise weight, for example, can be dumbbell or a kettlebell or some other type of exercise apparatus. It includes a housing that has opposingly angled inner surfaces. Removable weight pieces are shaped to wedge between the opposingly angled inner surfaces, and the housing supports the weight pieces. A movable holder secures the weight pieces and holds the weight pieces within the housing.
