Abstract: A smartwatch assembly including an outer frame portion and an insert portion removably insertable into the outer frame portion. The insert portion may include a casing, a controller disposed within the casing, an electrocardiogram sensor operably coupled to the controller, the electrocardiogram sensor having at least two electrodes configured to be placed in contact with a user's skin, a photoplethysmography sensor operably coupled to the controller and oriented to face the user's skin, and a display operably coupled to the controller and configured to show data related to measurements taken by the electrocardiogram sensor and the photoplethysmography sensor. The photoplethysmography sensor may detect trigger events in a heart function of the user, and, in response to the detection of a trigger event, the electrocardiogram sensor may initiate an electrocardiogram measurement of the user.

Abstract: A smartwatch assembly may include a dial portion having a plurality of apertures extending therethrough and a circuit board having a plurality of LED modules disposed thereon. The plurality of LED modules may be oriented to emit light toward the plurality of apertures of the dial portion. The circuit board may include a control module configured to illuminate the plurality of LED modules in response to an alert and a communication module configured to interface with an electronic device wirelessly and to receive the alert. Methods of making a smartwatch assembly may include disposing a dial portion having a face plate and a plurality of hour-mark apertures extending through the face plate in a watch casing and disposing a circuit board having a plurality of LED modules disposed thereon in a watch casing, the plurality of LED modules corresponding to the plurality of hour-mark apertures.

Abstract: A battery charger comprises a housing, charging means in the housing which, in use, for connection to an electrical outlet and an upper plate releasably attached to the housing, the upper plate having battery receiving means to accommodate a predetermined size battery, the housing being adapted to receive upper plates which differ in formation so as to receive batteries of different dimension.

Abstract: A holder typically for a portable telephone comprises an upper housing and a lower housing, the latter being adapted for fixing to a surface or object. The upper housing comprises a support plate upon which the telephone may be located, and a pair of movable gripper members which urge the telephone against a fixed member so as to be held firmly therebetween. The distance between the fixed member and movable gripper members may be varied according to the dimensions of the telephone which the holder is receiving, and biasing means on the movable gripper members are provided to insure that there is sufficient force to firmly hold the telephone in the holder between the movable and fixed gripper members.
