Abstract:
An optical switch () for alternatively redirecting a source beam () includes a director assembly () that is selectively moveable between (i) a first switch position (), (ii) a second switch position (), and (iii) a dual switch position (). In the first switch position (), the source beam () passes to a first port (). In the second switch position (), the source beam () is directed to a second port (). In the dual switch position (), the director assembly () splits the source beam () into a first beam part (A) that is directed to the first port (), and a second beam part (B) that is directed to the second port ().

Abstract:
Coil arrays are disclosed for a planar or linear motor. An exemplary coil array includes multiple coil modules. Each coil module includes at least one coil set, respective electrical circuitry to and from the coil set, at least one respective hydraulic cooling device for the coil set, and respective hydraulic conduitry to and from the cooling device. The coil modules are interchangeably mountable relative to each other in the array such that mounting the coil module to the array produces accompanying hydraulic and electrical connections between the array and coil module, and removing the coil module from the array severs the connections.

Abstract:
A pool cleaner is provided of the type powered by a suction or vacuum source, such as by connecting the pool cleaner via a vacuum hose or the like to the suction side of a conventional pool water filtration system. The pool cleaner comprises a compact housing carried on wheels for rolling movement along a submerged pool surface. A debris intake nozzle is formed at a lower end of the housing in close proximity with the pool surface, and communicates through a turbine chamber in the housing to the vacuum hose for water-borne vacuuming of debris from the pool surface. Water draw through the turbine chamber rotatably drives a turbine which in turn powers a drive train to rotatably drive the cleaner wheels together with a downforce fan for improved wheel traction. In addition, the drive train operates at least one timer cam for periodically actuating a reverse clutch assembly to drive at least one of the cleaner wheels in reverse for a brief time interval. The timer cam may also function to open a bypass door venting the turbine chamber to partially relieve the vacuum at the intake nozzle during the reverse drive mode.

Abstract:
A floating skimmer is provided for use with a pool cleaner of the type powered by a suction or vacuum source, such as by connecting the pool cleaner via a vacuum hose or the like to the suction side of conventional pool water filtration equipment, wherein the floating skimmer is coupled along the vacuum hose and functions to collect debris picked up by the pool cleaner as well as floating debris such as leaves and the like on the pool water surface. The floating skimmer comprises a buoyant housing having a perforated collection basket therein defining a primary debris collection chamber adapted for in-line connection along the vacuum hose to capture debris entrained with water drawn from the suction-powered pool cleaner to the filtration system. The perforated basket additionally defines a secondary debris collection chamber for capturing floating surface debris drawn over at least one weir, with a flow control valve assembly regulating the weir surface flow to insure that a sufficient flow is drawn through the pool cleaner for proper pool cleaner operation. A water level regulator float responds to the water level within the skimmer housing to variably open and close submerged auxiliary intake ports therein to maintain the water level generally between predetermined maximum and minimum limits.
A flow controller is provided for use with a pool cleaner, particularly of the type powered by a suction or vacuum source via a flexible vacuum hose or the like connected to the suction side of conventional pool water filtration equipment, wherein the flow controller maintains the suction pressure applied to the pool cleaner at a substantially constant and adjustably preset level consistent with substantially optimized pool cleaner operation. The flow controller comprises a generally tubular housing mounted at a location submerged within the pool water, preferably by installation in-line along the vacuum hose coupled to the pool cleaner. The flow controller includes a pivotally mounted flap valve biased by a spring for normally closing a bypass relief port. The flap valve is drawn by suction pressure toward a modulated open position to prevent the suction pressure from exceeding a preset threshold level. An adjustment knob on the flow controller housing is rotatably coupled to the biasing spring for adjustably increasing or decreasing the spring closure force applied to the flap valve, thereby adjustably setting the threshold suction pressure at which the flap valve opens the bypass relief port.

Abstract:
A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.
