Abstract: A portable electronic device may include a housing having a wall defining an opening in the housing and at least a portion of four side surfaces of the portable electronic device. The portable electronic device may further include a display at least partially within the housing, a front cover positioned in the opening in the housing and over the display, the front cover defining a front surface, a peripheral side surface extending from the front surface and at least partially surrounded by the wall of the housing, and a notch that, together with a portion of the wall of the housing, defines an acoustic port of the portable electronic device. The electronic device may further include an acoustic port cover positioned at least partially in the acoustic port and a speaker at least partially within the housing and configured to direct sound through the acoustic port cover.

Abstract: A pneumatic animal stunner for stunning an animal for later processing uses sensor technology to measure the speed of a stunning rod disposed in the stunner housing as it is driven forward via pneumatic forces. At least one sensor may be disposed in a nose connected to a front end of the housing, in the housing, or in a tail end of the housing. The at least one sensor communicates with a receiver that can process and display the speed data collected from the at least one sensor as the stunning rod drives forward. The receiver can be disposed on the housing of the stunner, or may be a separate component from the stunner. The data may be sent from the at least one sensor to the receiver via a wireless or wired connection. Multiple methods of measuring the stunning rod speed may be employed.

Abstract: Methods and systems are disclosed for electrically stimulating a nerve to cause muscle contraction. In one arrangement, a plurality of electrodes is positioned in contact with skin. The electrodes allow electrical stimulation to be directed independently towards a plurality of different stimulation regions below the skin via a corresponding plurality of combinations of the electrodes. For each combination of electrodes, a test stimulation is applied using the combination of electrodes and a response to the test stimulation is measured. One or a subset of stimulation regions is selected based on the measured responses. A therapy stimulation is applied to each selected stimulation region using the combination of electrodes corresponding to the selected stimulation region.

Abstract: An apparatus and method of use for a cartridge-type animal stunner comprising an elongated stunner housing having a muzzle and a breech with a cartridge chamber for receiving an explosive charge. A captive penetrating-type stunning rod capable of being propelled forward is received in the bore. The stunning rod has an opening throughout the entire length thereof. Upon placement of the housing forward end against an animal and activation of a trigger, a firing pin moves to impact a cartridge in the cartridge chamber, causing explosion of the cartridge. The stunning rod is propelled forward to penetrate the animal head to a brain. Simultaneously, a portion of combustion products from explosion of the cartridge travel into the stunning rod opening at a rearward end, along the length of the rod, and out of the stunning rod forward end into the animal brain to cause rapid lethal damage thereto.

Abstract: An actuation arrangement for effecting actuation of pivotable vane, for example, variable inlet guide vane in gas turbine engine. The actuation arrangement includes an actuator having a support plate and pivotable plate. The pivotable plate is fixedly connected to pivotable vane and pivotable plate and pivotable vane are pivotable about a pivot axis. The actuator further includes at least one actuation element having a length extending from support plate to proximal a transverse edge portion of pivotable plate substantially perpendicular to pivot axis. The or each actuation element is fixedly connected to each of the support and pivotable plates and formed of a material that changes dimension upon application of external energy. Thus, upon application of external energy, for example, heat, a change in length of the or each actuation element occurs such that change in length effects pivoting of pivotable plate and pivotable vane about the pivot axis.
