A cam-lock water gate designed to control water flow from a pond, lake, field, canal or the like. A primary body member is provided with an aperture therethrough and a short section of pipe stub integral with the main body member and opening into said aperture. An adjustable gate plate is mounted on said main body member and constrained between parallel guide channels to permit the gate to be adjusted for completely opening the aperture, partially opening the aperture, or completely closing the aperture. A regular duty embodiment employs a simple handle and rod control for both adjusting the gate plate as well as locking the cam-lock mechanism to positively retain the gate plate in the set position once adjusted. Another heavy duty embodiment employs heavier materials and heavier construction of the device and also incorporates a security lock bar that enables the gate plate to be locked to prevent unauthorized adjustment thereof. Another embodiment employs a threaded rod with adjusting nut operated by a wheel type control. A modified cam-lock mechanism is also incorporated for locking the gate plate in adjusted position. Rustproof and corrosion resistant materials are used for construction throughout all of the embodiments. Because of the lightweight construction employed all of the devices may be installed without the use of heavy equipment for most installations.

A pressure cuff is provided, comprising a plurality of layers and a controller. The layers comprise: an outer covering, an outer surface of which is exposed when the pressure cuff is secured around a body part of a patient; a first conductive layer; a first insulating layer separating the outer covering and the first conductive layer; an inner covering, the inner surface of which contacts the patient or the patient's clothing when the pressure cuff is secured to the patient; a second conductive layer; a second insulating layer separating the inner covering and the second conductive layer; and a first piezoelectric support layer separating the first and second conductive layers. The controller is electrically coupled to the first and second conductive layers and configured to supply a voltage to the first and second conductive layers, whereupon the first piezoelectric support layer constricts around the body part of the patient.

Some computer applications, such as database applications, generate sparse arrays that map identifiers to field values. To reduce memory usage, only those blocks of the array with non-empty entries are stored, and only the entries between and including the first non-empty entry and the last non-empty entry are stored. The offset and length of this range of non-empty entries is stored. To retrieve a value for an entry of the array, it is determined whether the entry is in an empty block or a non-empty block. If the entry is in an empty block, a null value is returned for the entry. If the entry is not in the stored range of entries for a non-empty block, a null value is returned for the entry. Otherwise, the value stored in the block for that entry is returned.

An automobile gear shifter kit includes a handle member, a trigger member and an actuating mechanism. The handle member is capable of being removably coupled to a gear shifter shaft of an automobile. The handle member includes an inner surface and an outer surface. The inner surface is configured to define a cavity portion and the outer surface is configured to provide a pilot control grip. The trigger member is disposed on the outer surface and is capable of triggering actuation of at least one of shifting of gears of the automobile and an operation of pre-determined auxiliary function of the automobile. The actuating mechanism is disposed in the cavity portion and is operatively coupled to the trigger member for being triggered by the trigger member for actuating the at least one of the shifting of the gears of the automobile and the operation of pre-determined auxiliary function.
