Patent CA-2638004-A1 (CA)
Inventor: CLARK ANTHONY JOHN
IPC: E05B57/00
Filed: 2007-01-31
Abstract: A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm.  Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.

Title: Charge-integrating retinal prosthesis and method
Inventor: MCLEAN GEORGE
IPC: A61F9/00
Filed: 2006-12-19
Abstract: A retinal prosthesis that provides power control capabilities through the temporal integration of electrical charge is provided. The retinal prosthesis comprises at least one stimulating component, each stimulating component in turn comprising a photojunction element (e.g., a photodiode) in electrical communication with an electrode. A pulse generation circuit provides a reverse-bias signal and, from time to time, a pulsatile forward-bias signal to the photojunction element. During application of the reverse-bias signal, light incident upon the photojunction element causes electrical charge to be accumulated. Upon application of the pulsatile forward-bias signal, the accumulated electrical charge is injected via the electrode into retinal tissues, thereby stimulating the retina. By appropriately selecting the bias signal parameters, a sufficient amount of charge may be accumulated to ensure reaching stimulation thresholds. In this manner, control over stimulus currents may be improved while still retaining advantageous use of the eye's natural focusing and imaging capabilities.

Title: Reduced opening elastic drawstring bag
Inventor: ROSS MICHAEL A
IPC: B01J21/04
Filed: 2009-09-03
Abstract: The present invention is directed toward an improved construction of an elastic drawstring trash bag. The elastic drawstring trash bag described herein is comprised of a plastic bag made from two panels. An elastic drawstring is provided within hems running along the top of the two panels. The upper opening of the elastic drawstring bag is reduced (when the bag is in a relaxed state) by decreasing the distance between the interior edges of the short seals used to weld the drawstrings and bag together. Like an ordinary non-elastic drawstring bag, the elastic drawstring is pulled through access cutouts centrally located along the upper edge of the bag. When the bag of the present invention is in a relaxed state, the reduced upper opening width of the elastic drawstring bag is therefore less than bag proper width, allowing a consumer to pull the elastic drawstring bag over the lip of a trash receptacle and allowing the elastic drawstrings to snugly fit around the trash can.
