Abstract: A wearable device has a housing containing electronics and a band that retains the wearable device on a user's arm. Each end of the housing has an open receptacle. The band has protrusions made from an elastomeric material and includes a rigid member arranged at least partially within. The protrusions are inserted into the receptacle to attach the band to the housing. A lower portion of the housing comprises two pieces that, when assembled, provide optical baffles between adjacent optical devices such as a heart rate monitor, and windows for the optical devices to operate. A thermal conductor is retained between the two pieces and facilitates operation of a temperature sensor in the device. An antenna carrier facilitates installation of an antenna without impairing fixation of an upper portion of the housing. A compact charger clips to the housing to supply power to recharge a battery in the wearable device.

Abstract: A wearable device has a housing containing electronics and a band that retains the wearable device on a user's arm. Each end of the housing has a receptacle with a ridge around the opening of the receptacle. A band comprises a strip of flexible material. A pair of protrusions with enlarged ends made from an elastomeric material extend from an inner surface of the band. A portion of the inner surface of the band between the protrusions is in contact with at least a portion of an upper surface of the housing. The band is joined to the housing by aligning each protrusion with a corresponding receptacle and applying pressure. As a result of the applied pressure part of the protrusion temporarily deforms, enters the receptacle, and resumes substantially the previous shape thus holding the protrusion within the receptacle and the band to the housing.

Abstract: A dock includes a first section and a second section joined with a spring hinge assembly. An applied force opens the dock and a device may be placed within the dock. The first section includes a first concavity which approximately conforms to a top surface of the device. Within the first concavity is a ridge which comes into contact with part of the top surface of the device. The second section includes a second concavity within which a bottom surface of the device fits. Electrical contacts such as pogo pins within the second section come into contact with electrical contacts on the bottom surface of the device. Annular elastomeric features around at least some of the pogo pins have a top edge which may come into contact with the bottom surface of the device. The spring hinge applies a force that closes the dock, retaining the device therein.
