Abstract:
Disclosed are devices, systems and methods for managing parking monitoring and enforcement. Parking at a meter or in a parking lot or ramp can be provided as a subscription. A registration and verification process for the subscription service can be provided as a multi-step process that combines the smart parking meter with a QR code, a mobile parking app for a smartphone, a central parking management system, and digital images of the parked vehicle(s). The registration process verifies that only vehicles owned by the subscriber are associated with the subscriber's account. Steps can also be employed to ensure that subscribers are not incorrectly issued parking citations by determining whether license plate data for a vehicle initially determined to be in violation matches an active subscription parker's roster of registered vehicles.
Abstract:
A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

Abstract:
A coil assembly comprises a coil (24) wound upon a bobbin (32). A pair of terminals (34) is upported by the bobbin (32). The coil (24) has a pair of lead wires, each of which is connected to one of the terminals (34). Each terminal (34) is adapted to be coupled to an electronic control unit. The coil (24) is enclosed at least in part by a flux return casing (26). At least one resilient member (46) is arranged and configured to urge the bobbin (32) and the casing (26) axially downward. The resilient member (46) can be included in a coil spacer that is disposed between the coils (24) and a printed circuit board.
Abstract:
An electromagnetic valve (32) for use in controlling fluid flow between first and second passageways (P1, P2) in a hydraulic valve block (4), includes a valve body (51). The valve body (51) defines a central axis (A), has a central opening (51A) therethrough, has a lower end (54) adapted to be inserted into a bore (19) of the valve block (4), and is provided with a lower cylindrical opening (70). An armature (56) is axially moveable within the valve body (51) and is biased by a spring in one axial direction (57A). A closing element (88) is carried by a lower end (54) of the armature (56). An electromagnetic coil (64) coaxially surrounds the armature (56) and is operable to effect axial movement of the armature (56) in an axial direction opposite the one direction (57B). A valve seat member (62) is carried by the lower end (54) of the valve body (51) and has an orifice (98) providing fluid flow between the first and second valve block passageways (P1, P2). The valve seat member (62) defines a valve seat (96) surrounding the orifice (98) and cooperates with the closing element (88) for selectively closing the orifice (98). The valve seat member (62) includes a cylindrical tubular portion (90) frictionally retained in the lower cylindrical opening (70) of the valve body (51). The lower cylindrical opening (70) of the valve body (51) is provided with a stop surface (68) at the upper end of thereof, and an upper part (92) of the cylindrical portion (90) of the valve seat member (62) includes a flange (100) engageable with the stop surface (68) for limiting downward movement of the valve seat member (62) relative to the valve body (51).
Abstract:
A method of manufacturing an armature assembly for a valve includes providing powdered metal. The powdered metal is then placed in a die having a cavity defining the shape of an armature core. Pressure is then applied to the powdered metal in the die so as to compact the powdered metal into the shape of the armature core. The powdered metal of the armature core is then heated so as to bond the powdered metal, thereby forming a paramagnetic armature core.
