Abstract: A wireless charging system includes an electrical and/or electronic interconnect as first connector. The transmitter electronics are included in the first connector. The first connector is electrically connected to a second connector via a cable. The second connector includes a transmitter coil. The first connector, cable, and the second connector are form the transmitter portion of the wireless charging system. Information from a receiver is obtained by the first connector which demodulates and processes the information and based on the request from the receiver changes the impedance and switching frequency of a tank circuit of the transmitter coil. Efficiency of the wireless charging system is optimized while reducing the form factor.

Abstract: Devices, systems, and, methods for measuring deformation variation in an insole to determine characteristics of a user, including weight and gait, are described herein. In some embodiments, a device includes an insole having a fluid reservoir configured to be disposed in a shoe, a deformation sensor, and a communications module. The fluid reservoir includes a first portion and a second portion. The deformation sensor is coupled to the fluid reservoir and is configured to measure a deformation in at least one of the first portion and the second portion. The communications module is configured to receive the measured deformation from the deformation sensor and transmit the measured deformation to a remote device.

Abstract: A caseback has multiple, arc-shaped, ferrous, metal contacts that serve a dual purpose. The metal contacts i) establish an input connection between a battery for the wearable electronic device and charging prongs of a charger and ii) establish a magnetic coupling between the wearable electronic device and multiple magnets in the charger to hold the metal contacts of the wearable electronic device and the charging prongs of the charger in place during a charging of the battery. A male extension extends from a surface of the caseback to couple into a female receptor of the charger. i) The ferrous metal contacts' relationship with a positioning of the magnetics in the charger in combination with ii) the male extension coupling into the female receptor use magnetic and mechanical coupling to establish and control an alignment of the metal contacts with the charging prongs in three dimensions, a Z-axis, an X-axis, and a Y-axis.

Abstract: A method for displaying representations of facial expressions on devices includes receiving, by a processor on a device, data from a sensor coupled to the device. The method includes identifying, by the processor, responsive to the received data, a level of progress that a user of the device made towards a goal. The method includes selecting, by the processor, responsive to the identification, an icon representing a facial expression. The method includes modifying, by the processor, a level of power for each of a plurality of light indicators embedded in the device to display the icon.

Abstract: A device includes a housing constructed from a conductive material, and an electronic circuit electrically insulated from the housing. The device also includes a power source positioned such that a first electrical contact of the power source faces the electronic circuit and a second electrical contact faces a side of the housing. The device also includes an insulating layer that includes a first aperture and a second aperture. The device also includes a first connector configured for electrically coupling the electronic circuit and the first electrical contact, and a second connector configured for electrically coupling the electronic circuit and the side of the housing via the first aperture of the insulating layer. The power source is configured for electrically coupling the second electrical contact with the side of the housing via the second aperture of the insulating layer.

Abstract: A band may include a plurality of interlocking links or link adjustment mechanisms. An interlocking link or link adjustment mechanism may include a rotating member on a first side, and a static member on a second side. The rotating member may rotate as much as approximately ±45 degrees with respect to a horizontal axis of a pin in an open/unlocked position. Interlocking links or link adjustment mechanisms may interlock with one another, and the rotating member of a first interlocking link or link adjustment member may rotate to a closed/locked position. In the closed/locked position, a pin of a second interlocking link or link adjustment member may be fully inserted into the pin aperture provided by the rotating member of the first interlocking link or link adjustment member. The pin may include a pin end that may provide a spring-loaded connector that may be secured in the pin aperture.

Abstract: A bracelet may be adjustable. The bracelet may be a portion of a watch and/or jewelry. The bracelet may include a clasp with a track that includes a plurality of first openings and second openings. A first end of the bracelet may include a link with a pin. The pin may be disposed in the track, and the length of the bracelet may be adjusted by moving the pin along a length of the track. The pin may have a length and a cross-sectional shape perpendicular to the length. The cross-sectional shape may allow the pin to travel along the length of the track when the link is disposed at an angle relative to the length of the track and may restrict the pin from travelling along the length of the track when the link is approximately parallel to the length of the track.

Abstract: A timepiece may include a movable case that may rotate approximately 180 degrees with respect to a first link and a second link. The case may include a first pair of tracks and a second pair of tracks that may be provided on opposite sides of the case. A first link and a second link may each slidably engage both the first pair of tracks and the second pair of tracks, so that the case may rotate 360 degrees about the first link and the second link.
