Abstract: Embodiments described herein provide for a satellite device that can be associated with a user account of a minor aged (e.g., child or adolescent) user that does not have a smartphone that can be used as a companion device to the satellite device. The satellite device can be configured to be used as a primary device, without reliance upon a paired smartphone. Certain information can be synchronized with the satellite device via the association with the family account. During initial configuration, a set of cryptographic keys can be generated to associate the account of the satellite device with the set of accounts in the family. The satellite device can then access calendars, media, or other data that is shared with user accounts within a family of user accounts.

Abstract: Embodiments of the present invention are directed to interface devices that provide an interface between a first device and a second device, where the interface device provides electrical isolation between the first device and the second device, and where codec processing is distributed between the first-device side and the second-device side of the interface device. In a preferred embodiment, the second device has a transmission line, the interface device is a modem, and the electrical isolation is provided by one or more digital couplers that transmit sigma-delta signals that are coded and decoded in both the first-device-side and second-device-side circuitries of the modem.

Abstract: A peak catcher circuit comprises an input differential amplifying circuit consisting of a pair of transistors. An input signal in the form of an electrical wave or pulse is applied between the base of the first transistor of the pair and a point of fixed potential, while a capacitor is connected between the base of the second transistor of the pair and the fixed potential. A first fixed current source is connected between the coupled emitters of the differential pair and the fixed potential, and a second smaller fixed current source is connected between the collector of the second transistor and a second fixed potential. A second pair of oppositely poled emitter-coupled, common base connected transistors is connected between the base of the second transistor of the differential pair and the second fixed potential, and there is a connection from the coupled emitters of the second pair to the collector of the second transistor of the differential pair.
