Abstract: A system includes an ocular device (10) for deployment in or on an eyeball, and an external device (12). The external device has an electrically-actuated energy-transmitting component (16) for mounting in proximity to the eye, and preferably on an external surface of an eyelid of a user so as to move together with the eyelid. Driver circuitry (22) actuates the energy-transmitting component to transfer energy wirelessly to an energy receiver of the ocular device. Some implementations employ near-field resonant coupling between the external device (12) and the ocular device (10), and support data transfer therebetween, optionally via modulation of the transferred power.

Abstract: Chimeric polypeptides comprising a dihydrotestosterone (DHT) reductase moiety, such as 3 alpha-hydroxysteroid dehydrogenase (3?-HSD), fused to a signal peptide moiety, polynucleotides encoding same, and compositions comprising at least one microorganism cell capable of secreting the chimeric polypeptide, are provided. Further provided are methods and kits for treating, preventing or ameliorating androgen-dependent disorders, including but not limited to androgenic alopecia.

Abstract: An insert for a pressure sealant type sealing system, an improved sealing system for sealing between an aperture of a machine housing and a rotating shaft of the machine protruding through the aperture, comprising the insert to provide a pair of outlets into the driveshaft arranged collinearly around the driveshaft, a method of injecting the sealant into the stuffing box in two positions on opposite sides of the drive shaft thereby balancing the pressure, and a method of retrofitting existing pressure sealant systems by retrofitting with the insert.

Abstract: A conduit for a cooling liquid, said conduit for substantially contacting a viscous fluid type sealant within a stuffing box, thereby conducting heat away from said sealant within said stuffing box by flowing said cooling liquid though said conduit.

Abstract: A sealing system for sealing between an aperture of a machine housing and a rotating machine-shaft protruding through the aperture, said sealing system comprising: (i) a stuffing box for encasing the aperture of the machine housing and a segment of said shaft and, (ii) a viscous fluid type sealant within said stuffing box, wherein the shaft is concentric about its axis of rotation and said segment has at least one variation in its effective external diameter thereby increasing the surface area thereof, in contact with the liquid sealant.

Abstract: A tag interrogation system including at least one base station and a plurality of tags, each having an awake mode and a sleeping mode, wherein each base station is operative to broadcast messages which are received by the plurality of tags and has a receiving window during which it is operative to receive messages sent by individual tags from among the plurality of tags, and wherein at least some of the messages broadcast by at least some of the base stations include an indication of the time at which a future receiving window is due to open, thereby to allow tags to conserve power by remaining in the sleeping mode until the future receiving window opens.

Abstract: A computerized fluid supply system including a controller controlling at least supply of a fluid via a fluid fill nozzle to a tank, a fluid tank mounted identifier, a fluid fill nozzle mounted tank identification reader assembly, the fluid fill nozzle reader being in wireless communication with the tank identifier for receiving tank identification information therefrom and with the system controller, the fluid fill nozzle mounted tank identification reader assembly including a conduit portion connected in series with the nozzle and electronic circuitry mounted exteriorly of the conduit portion.

Abstract: A shelving system features two spaced apart pairs of support rods deployed roughly vertically with a number of shelf assemblies supported thereby. Each shelf assembly is constructed from an open ended, molded polymer shelf having two openings in the upper surface adjacent to each of the open ends, and two suspension inserts engageable within the open ends. Each suspension insert has a pair of vertical bores, aligned with the openings when assembled, which are configured for forming suspension joints with the support rods. Since the precision vertical bores are contained within the separate suspension inserts, the main body of the shelf can be molded by techniques employing primarily longitudinal movement of mold parts, i.e., along the longest dimension of the shelves. In a preferred embodiment, each shelf is formed with support elements of closed cross-section extending along most or all of its length. Also disclosed is a snap-on drawer assembly for attachment to the underside of one of the shelves.

Abstract: An injected plastic cabinet comprising a top, a bottom, a back wall, and left and right side walls being connected together, forming a box having a front opening, and at least one door element being hingedly connected to at least one of the left and right side walls for covering the front opening, wherein each of the back wall, left and right side walls and each of the door elements is at least 160 centimeters in height and is a product of a single plastic injection.
