Abstract: An intrauterine contraceptive system may include a contraceptive intrauterine device, a retrieval thread permanently attached to the intrauterine device and an insertion device for inserting the intrauterine device into a uterus. The system may also include a release thread releasably coupled with the intrauterine device. The intrauterine device may be deployable out of a distal end of the insertion device and may be configured to change from a delivery configuration when housed in the insertion device to a deployed configuration when deployed in a uterus. The retrieval thread and the optional release thread may be at least partially housed within the insertion device during insertion of the intrauterine device into the uterus. The release thread may extend from the intrauterine device through the insertion device to an attachment point at or near a proximal end of the insertion device.

Abstract: The handle includes first and second spaced sets of prongs. Each of the prong sets has a first prong and a second prong spaced from the first prong a distance sufficient to receive the cookware rim therebetween. The prongs in each of the prong sets diverge as the prongs progress away from the cookware body. A locking mechanism is situated between the prong sets for engaging the cookware rim to removably secure the handle to the cookware. The locking mechanism includes a spring-loaded pin adapted to be received in an opening in the cookware rim. The pin is situated on the unattached end of a leaf spring prong extending from the body of the handle. The pin has an inclined surface which facilitates the insertion of the pin into the opening in the cookware rim to lock the handle to the cookware. The handle is formed of a single piece of material and may be sold in combination with the cookware or separately.

Abstract: Systems and methods for pairing for-hire vehicles with their associated medallion are disclosed. Some for-hire vehicles, such as taxis operate with a for-hire vehicle meter (taximeter). In some embodiments, the meter contains an identifier of a medallion that is associated with the meter. The meter may then determine if it is connected or properly associated with the medallion. If the meter is connected or properly associated with the medallion, it will then access the identification information of the medallion and determine if identification information matches its contained medallion identifier. If the identification information does not match, the meter may shut down and thereafter be non-engageable. The relationship between the medallion and the meter is advantageously used to enforce restrictions on the operation of the for-hire vehicle including, for example, time and location of pick-up restrictions.

Abstract: The profile shape of the vessel body and of handle portion is formed from a single sheet of metal to create a flat by cutting, stamping or blanking. An opening is created in the handle portion to reduce heat propagation. The shape of the pan body is formed by spinning with the flat handle portion. The handle is formed by creating three-dimensional contours in the handle portion of the blank. The neck portion has a flat section adjacent the pan body followed by sections of different curvature. One section of the neck portion has a deeply curved cross-section. That neck portion transitions to the hand grip portion which has a reduced curvature, particularly toward the unattached end of the handle. The neck portion may have a “W” cross sectional shape. The handle grip portion may have a “U” shaped cross-section for comfort.
