Abstract: A novel embodiment of a pump system, for example, of the type that would be used in a wearable drug delivery system, comprises, in a preferred embodiment, a reservoir, a plunger, disposed within the reservoir and driven by a scissor mechanism connected to a drive mechanism through a linkage, such that a force imparted by the drive mechanism in causes the scissor mechanism to expand thereby causing the plunger move within the reservoir to force a liquid drug contained within the reservoir through a fluid port to a patient.

Abstract: A method of controlling a memory and a memory controller are disclosed. The memory controller is operable to control a memory, the memory being operable in a plurality of modes, the memory controller comprising: memory interface logic configurable to interact with the memory in each of the plurality of modes; and memory mode change logic operable, in response to a memory mode change request instruction specifying a predetermined one the plurality of modes being issued by the memory interface logic to the memory, to request the memory interface logic to be configured to interact with the memory in the predetermined one of the plurality of modes and to prevent interaction between the memory interface logic and the memory until the memory interface logic confirms that it is configured to interact with the memory in the predetermined one of the plurality of modes.

Abstract: A relay socket is attachable to a cutout in a panel. The relay socket includes a base, at least one rocker beam or heel element at one side of said base, and at least one active snap element at the opposite side of said base. The elements are constructed and arranged so that the socket may be inserted into place by engaging the rocker beam element on one side of a cutout in a panel and pivoting the active snap element toward the opposite side of the cutout so that it engages the opposite side of the cutout and moves inwardly and is inserted into the cutout in which position it moves outwardly to engage the opposite side of the cutout. In this way the elements cooperatively hold the socket onto the panel. There is also an assembly which includes the relay socket. This assembly includes the panel with a cutout into which the relay socket is to be attached as well as the relay itself on the other side of the panel from the relay.
