Abstract: Various embodiments of the present disclosure include a mechanical broadhead for use with an archery bow and arrow. In certain arrangements, a broadhead is provided that maintains the cutting blades in a retracted or closed position during flight of the arrow. Upon target contact, the blades expand outwardly from the closed position.

Abstract: A device for controlling access to a firearm having a muzzle with a muzzle device. The device includes a lock housing with a cavity to receive the muzzle device and a portion of the barrel. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the muzzle of the firearm occupying the full length of the firearm's muzzle device, barrel and chamber. The device also includes a plurality of arms coupled to a perimeter of the cam and arranged for pivotal and radial movement to secure the firearm muzzle in the cavity of the lock housing. A plurality of tabs are arranged on the arms for engagement with the muzzle device to retain the muzzle device within the lock housing.

Abstract: A semiautomatic handgun includes various unique features to facilitate rapid, accurate shooting. Some examples of the handgun include a more compact recoil spring system, locating the recoil spring around the barrel while permitting rearward movement of the barrel in conjunction with the slide. Other examples include an automatic magazine release for releasing the magazine upon the discharge of the last cartridge in the magazine. Still other examples include a grooved or roughened top slide surface for facilitating slide manipulation with one hand. Further examples include auxiliary sight systems to facilitate determining the proper distance by which to lead a moving target. Other examples include a takedown tool stored within the handgun.

Abstract: A multiple-field-of-view scannerless optical rangefinder operating in pulsed Time-Of-Flight operation for use in high ambient background light is described.

Abstract: There is provided a steering shaft modifier, capable of fundamentally preventing distortion generated in a new steering shaft, being easing aligned, and being simply assembled, including: a frame having a steering shaft penetrating portion formed in a front surface thereof and having a contact surface covering a portion of the steering head and disposed to be in contact with an upper bearing installation portion of a steering shaft installation portion; a shaft including a head portion caught by a lower bearing installation portion of the steering shaft installation portion of the steering head, a body portion passing through the steering shaft installation portion, and a connection portion connected to the frame; and a frame block including a lower contact surface tightly attached to a lower surface of the steering head in the rear of the lower bearing installation portion and coupled to the frame when installed.

Abstract: A LIDAR device may transmit light pulses originating from one or more light sources and may receive reflected light pulses that are then detected by one or more detectors. The LIDAR device may include a lens that both (i) collimates the light from the one or more light sources to provide collimated light for transmission into an environment of the LIDAR device and (ii) focuses the reflected light onto the one or more detectors. The lens may define a curved focal surface in a transmit path of the light from the one or more light sources and a curved focal surface in a receive path of the one or more detectors. The one or more light sources may be arranged along the curved focal surface in the transmit path. The one or more detectors may be arranged along the curved focal surface in the receive path.

Abstract: The present invention is an ammunition magazine, preferably made of a reinforced polymer, utilizing a structurally enhancing ridge, angular guide rails and a follower made to interface with said guide rails to reduce wobble. The preferred embodiment also features a protective cover that distributes forces from the spring to more structurally sound areas of the magazine, thus reducing feed end splay, and an ammunition indication system comprised of at least one window and a noticeable marker on the follower spring. The follower and magazine casing are also designed to interface to prevent the follower from popping out of the feed end and the floor plate of the magazine utilizes a locking plate and sliding relationship between the floor plate, locking plate and magazine to secure the floor plate onto the magazine casing. The cover features built in tools for, among other things, unloading and disassembling the magazine.

Abstract: A method of detecting an early onset of neurocardiogenic syncope in a patient uses respiratory functions as a predictor of the syncope. According to the method, at least one sample of baseline minute ventilation, tidal volume and respiratory rate of the patient is obtained. The detection unit is set to detect an increase in tidal volume and in minute ventilation over a predetermined respiratory period. The detecting unit also detects any rate of change in respiratory rate and sends a signal to a microprocessor to determine whether the increase in minute ventilation is a sole function of increased tidal volume. The impending syncope is diagnosed if variance in respiratory rate is less than 25% in relation to the sampled baseline during the predetermined period of time.
