Disclosed herein are a vehicle or other system battery with a self-contained backup capability and a method for providing power to a vehicle using the vehicle or other system battery with a self-contained backup capability. In one aspect, the vehicle battery comprises, a main battery portion, a backup battery portion, and a control device for selectively communicating a transfer of energy from the backup battery portion to the main battery portion when a voltage level or other health indicator of the main battery portion is determined to be below a reference voltage threshold, wherein the main battery portion and backup battery portion are each re-chargeable via an alternator of the vehicle when the control device communicates the transfer of energy between the main battery portion and the backup battery portion.

A processing device in a memory sub-system detects a preemptive power loss condition in the memory sub-system and, in response, causes operations of a local media controller associated with a memory device in the memory sub-system to be suspended, wherein responsive to being suspended, the local media controller to perform power loss handling operations to complete a subset of a plurality of pending memory access operations, and wherein to perform the power loss handling operations, the local media controller to complete the subset of the plurality of pending memory access operations for which an acknowledgment signal has been sent to a requestor. The processing device further detects a full power loss and restore condition in the memory sub-system, responsive to detecting the full power loss and restore condition, initializes the memory device and causes operations of the local media controller to resume.

A combined data/power coupling device includes a chassis having first and second powering device connectors and a powered device connector each coupled to a data/power coupling subsystem. The data/power coupling subsystem configures each of the first and second powering device connectors to receive power from at least one powering device, configures the first powering device connector to receive data from the at least one powering device, and provides data and power received via the first powering device connector to a powered device via the powered device connector. When the data/power coupling subsystem determines that data and power are not available via the first powering device connector, it configures the second powering device connector to receive data from the at least one powering device, and provides data and power received via the second powering device connector to the powered device via the powered device connector.

One or more sampling parameters of an application associated with a downstream voltage regulator may be determined. A power supply rejection ratio (“PSRR”) and a switching frequency of an upstream voltage regulator may be dynamically adjusted based on the sampling parameters of the application associated with the downstream voltage regulator. The sampling parameters may include a noise level and a workload of the selected application.

An energy offloading system is in direct electric communication with an energy supply and dynamically receives energy from the energy supply. The energy offloading system uses energy for high-load computations. The energy offloading system includes computers performing the high-load computations as well as servers, cooling units, and communication devices. When the energy from the energy supply is terminated, the energy offloading system may power down these and other devices, or may switch these devices to an alternative power source. The energy offloading system may be portable.

Embodiments of the present invention provide a voltage protection apparatus (130, 160, 205, 630, 730), comprising an input (165, 210, 610, 710) to receive an input voltage provided to a processor (120), an output (190, 260, 680, 760) to output a throttle signal to the processor (120), a filter circuit (180, 240, 640, 660, 740) to filter the input voltage provided to the processor (120) to provide a filtered input voltage, and a first circuit (170, 230, 630, 650, 73) to compare the filtered input voltage to a first threshold voltage (175, 235, 635, 645, 735) and to cause the output (190, 260, 680, 760) to provide the throttle signal to the processor (120) indicative of the filtered input voltage dropping below the first threshold voltage.

A point-of-sale (POS) device includes a processor, a battery, a transaction object reader, a printer with a printer controller, and optionally a temperature sensor. The processor determines a present power discharge capability rate of the battery, optionally based on a temperature measured by the temperature sensor. The processor also calculates a first estimated power draw rate based on a first setting value for at least one of the components of the POS device, such as the printer. If the first estimated power draw rate is dangerously close to the present power discharge capability rate of the battery, a second estimated power draw rate is calculated based on a second setting value for the one or more components. If the second estimated power draw rate is no longer dangerously close to the present power discharge capability rate of the battery, the components are set to the second settings value.
