Abstract: A carrier for solid state devices includes a plurality of panels, at least one gate, and an addition. The plurality of panels includes a first panel, a second panel, and a third panel. The at least one gate is attached to the second panel and the third panel. The at least one gate is configured to be in one of a first position or a second position. When the at least one gate is in the first position, an opening for receiving solid state devices is at least partially occluded to a first width that is smaller than a length of one of the solid state devices. When the at least one gate is in the second position, the opening for receiving the solid state devices is increased to a second width that is larger than the length of the one of the solid state devices.

Abstract: A sensing circuit coupled to a sensor includes a first transistor, a second transistor, a third transistor, a fourth transistor, and an oscillator. The first transistor, coupled to a first current source and the sensor, receives a sensing current from the sensor. A gate terminal of the first transistor is connected to a source terminal of the first transistor. The second transistor, coupled to the first transistor and a second current source, generates a first current according to the sensing current. The first current is greater than the sensing current. The third transistor, coupled to the second transistor and the second current source, generates a second current according to the first current. The fourth transistor, coupled to the third transistor, generates a third current. The oscillator is coupled to the fourth transistor. The oscillator generates a signal having an oscillation frequency according to the third current.

Abstract: A carrier for different form factors for insertion in a slot of a computing device is disclosed. The different form factors have different thicknesses defined by the E1.S specification. The carrier includes a base holding a first type of form factor. A bezel is configurable for insertion in a slot for a device of the first type of form factor. The bezel has an attachment surface. The base is attachable to the attachment surface of the bezel. A second type of form factor is also attachable to the attachment surface of the bezel. A cover encloses the first type of form factor when joined to the base. The base and cover are discarded when the second type of form factor is attached to the bezel. The attached bezel and second type of form factor may also be inserted in the slot.
