  • Patent number: 9430008
    Abstract: A method includes detecting removal or depletion of a power supply associated with a powered device. The powered device is configured to receive power from a power adapter via a narrow-voltage direct current/direct current (NVDC) charger and from the power supply. The method also includes, in response to the detection, disabling a dynamic power management function of the NVDC charger. The method further includes monitoring input current or input power provided to the powered device by the NVDC charger and determining if the input current or input power exceeds a threshold. In addition, the method includes, if the input current or input power exceeds the threshold, triggering a throttling of an operating clock frequency of the powered device. The method could also include (i) disabling a specified mode of operation and turning on a voltage regulator of the NVDC charger in response to the detection and (ii) providing over-voltage protection.

  • Patent number: 9367723
    Abstract: A cordless, electro-optical reader is compatibly docked with different docking stations having station contacts located at different locations. A rechargeable battery is mounted in a housing that extends along a longitudinal axis. Multiple housing contacts are located on the housing. Some housing contacts conduct electrical power to recharge the battery; other housing contacts conduct electrical signals to and from a controller. Each housing contact has one exposed contact portion facing in a first direction, e.g., axially along the longitudinal axis, to make electro-mechanical contact with station contacts located at one location of one docking station, and another exposed contact portion facing in a different second direction, e.g., transversely of the longitudinal axis, to make electro-mechanical contact with station contacts located at another location of another docking station.

  • Patent number: 9345104
    Abstract: Systems and methods may provide for a power management apparatus including a first path to be coupled to an output of a narrow voltage direct current (NVDC) charger and an input of a backlight voltage regulator (VR). The apparatus may also include a second path to be coupled to an input of the NVDC charger and the input of the backlight voltage regulator, wherein the second path is to bypass current around the NVDC charger and to the input of the backlight VR if a voltage supplied by a first power source to the NVDC charger exceeds a voltage of a second power source coupled to the output of the NVDC. In one example, the first path includes a first diode and the second path includes a second diode, wherein the first and second diodes form an OR configuration for the apparatus between the first and second paths.

  • Patent number: 9246343
    Abstract: An example of a charging apparatus includes a housing, a first movable member, and a second movable member. The first movable member is configured to be pressed down. The second movable member accommodates a charging terminal in the housing in a reference state, and when the first movable member has been pressed down, causes the charging terminal to protrude through an opening portion provided in the housing, so as to enter a terminal contact state. The first movable member and the second movable member are configured such that an amount of movement of the charging terminal during a period from the reference state to a predetermined intermediate state is smaller than the amount of movement during the same period in a case where the charging terminal moves from the reference state to the terminal contact state by an amount proportional to an amount of pressing down the first movable member.

  • Patent number: 9225200
    Abstract: An electronic device includes a connection interface, a voltage regulation unit, a storage unit, a charging unit, a processing unit, and a switching unit. The switching unit is coupled to the storage unit, the processing unit, and the connection interface. When the electronic device is in a power-exhaustion state and an external device having a charging function is coupled to the connection interface to provide a first supplying voltage to a power pin of the connection interface, the voltage regulation unit transforms the first supplying voltage to a first operation voltage to power the storage unit and the switching unit, and the switching unit couples the storage unit to the connection interface to transmit device information to the external device. When the external device provides a second supplying voltage to the power pin in response to the device information, the electronic device is in a charging state.

  • Patent number: 9218043
    Abstract: A controller configurable to operate in either in an NVDC mode or a standard mode. The controller includes mode logic that detects a mode value indicative of the selected mode and that asserts a corresponding mode signal, and control logic that is configured to operate according to the selected battery charging mode based on the mode signal and that provides a control signal accordingly. In the standard mode, the control signal is in either an on or off state depending upon presence of an external adapter and the charge state of the battery. In the NVDC mode, the control signal may operate in a linear mode if the battery is deeply discharged. A battery detector provides a battery indication that is used to switch the regulation operating point of an external system voltage. A power monitor output provides an indication of power being provided via the system voltage.
