An example device includes a physical storage medium, a wireless power circuit, and a portable sealed housing containing the physical storage medium and the wireless power circuit. The physical storage medium stores a first security protocol to activate the wireless power circuit, and a second security protocol to allow data transfer between the physical storage medium and a host device.

Storage devices with secure power and data access

Example implementations relate to transmitting signals via USB ports. For example, a system according to the present disclosure, may include a host module including a plurality of USB ports, a first expansion module, and a second expansion module. The first expansion module may include a first USB port and a second USB port. The first expansion module may receive a signal from the host module at a first USB port, and direct the signal to a second USB port. The first expansion module may transmit the signal to a second expansion module via a second USB port.

Transmitting signals between USB ports

An example disclosed herein is a non-volatile storage medium including instructions relating to control of power that, when executed by a processor, cause the processor to monitor a supply of power to a regulator, decouple supply of power to the regulator when the monitored supply of power is below a predetermined level, couple a power pack to the regulator to supply power to the regulator when the monitored supply of power is below the predetermined level, and generate an Advanced Configuration and Power Interface (ACPI) G1 Sleeping state signal when the monitored supply of power is below the predetermined level.

Power controls

An example printed circuit board assembly (PCBA) includes a controller and a plurality of conductive contacts. The conductive contacts are coupled to the controller. The controller is to determine a type of chassis to which the PCBA is mounted.
