A method of aspirating a vascular occlusion from a remote site is provided. The method includes the steps of advancing a first elongate tubular body through a vascular access site and into a body vessel, advancing a second tubular body distally to extend beyond the first elongate tubular body to reach the remote site, and aspirating thrombus from the site into the lumen by applying pulsatile vacuum to the first elongate tubular body. The second tubular body has a lumen and a length that is shorter than the first elongate tubular body. The pulsatile application of vacuum may cause the distal tip of the second tubular body to open and close like a jaw, which facilitates reshaping the thrombus or biting or nibbling the thrombus material into strands or pieces to facilitate proximal withdrawal under negative pressure through the lumen of the second tubular body.

An insecticide packet for killing biting insects comprises an envelope enclosing an insecticide and having a permeable web that is penetrable by the mouthparts of a biting insect. The permeable web allows insect attractants to migrate from within the envelope to the ambient environment. The envelope may be enclosed within an outer protective pocket. The insecticide packet is provided with a plurality of pins extending outwardly from the packet to discourage non-targeted animals from attempting to ingest the envelope or its contents. The packet is provided with a buoyant support arranged so that the permeable web is above the water line when the packet floats on the surface of a water body. The insecticide includes a stomach poison mixed with a liquid food that is preferred by the biting insects, such as cattle blood. Volatile insect attractants may be added to the mixture of stomach poison and food.

The invention relates to a shearing control method and a shearing control device for circle shears. The method comprises the following steps: when the head of a steel strip reaches the front parts of entrance pinch rolls, a command sender takes the entrance pinch rolls as a speed command body to send a shearing and biting speed command; when the head of the steel strip reaches a main cutting edge, the command sender takes the main cutting edge as the speed command body, maintains the shearing and biting speed, and controls the entrance pitch rolls to follow and be synchronous with the linear speed of the main cutting edge; and when the head of the steel strip reaches exit pitch rolls, the command sender takes the main cutting edge as the speed command body to send an acceleration command, controls the main cutting edge to speed up to achieve the shearing speed required in a high-speed shearing command within 0.5 to 2 seconds, and controls the exit pinch rolls to follow and be synchronous with the linear speed of the main cutting edge. The control method and the control device effectively reduce instantaneous impact loads withstood by all mechanical parts at the time of biting, prolong the service life of shearing equipment, reduce maintenance cost, reduce the failure rate of a clamping chute at a cutting edge, and improve equipment stability and utilization rate.

An oropharyngeal device, for example, an endotracheal tube or a laryngeal mask airway, intended for insertion into a patient includes a tube portion defining a lumen which permits flow of a ventilating gas to the patient who may be under anesthesia for performance of surgery. The device includes a reinforcement member in a bite-resistant zone, which keeps the lumen open during patient biting to prevent occlusion of the lumen and/or interruption of the flow of ventilating gas. The reinforcement member can have a number of adjacent or closely-spaced wire turns or another suitable structure, and can cooperate with the tube portion to provide good bite-resistance. The tube portion optionally can be yieldable in the bite-resistant zone and provide cushioning during biting to inhibit dental or other damage.

The system detects and alerts an angler that fish are nibbling, biting, and/or striking.

The invention provides a speaker recognition method for deliberately pretended voices. Firstly, a reasonable recording scheme is set up in an anechoic room without noise and reflection for eight deliberately pretended voices, namely tone raising, tone lowering, quick speaking, slow speaking, nose nipping, mouth covering, object biting (holding a pencil in the mouth) and chewing (chewing gum), then based on pitch period presorting, the Mel frequency cepstrum coefficient and a Gauss hybrid model are used for carrying out recognition under pretending of a speaker, and finally self-adaptive group adjustment is adopted to achieve high-quality speaker recognition of pretended voices. The method can be applied to voice cases that criminals cover up identities through pretended voices.

An apparatus for attracting mosquitoes to an electronic insect killing machine (i.e., bug zapper) is provided. The apparatus includes a converter device that fits over a fluorescent or ultraviolet light bulb of the bug zapper. The converter device controls radiant light and heat emitted by the light bulb to produce a desired level of heat to create a warm mass, or host simulator that simulates a blood host meal for biting insects. Mosquitoes and other biting insects, which have infrared vision, are attracted to the host simulator. When used with a scented lure that lures the mosquitoes and biting insects near the insect killer, the host simulator lures the mosquitoes and other insects to the killing device of the insect killer. The mosquitoes and biting insects are destroyed once lured to the killing device. The converter device also blocks most of the visible light emitted by the light bulb, and therefore does not lure beneficial insects, which are attracted to visible light, into the insect killer.
