Abstract: The present invention provides 1,2,4-triazolo[1,5-a]pyrimidine-based compounds of formula (I), Formula (I) and pharmaceutically acceptable salts thereof, which have been found to be advantageously potent and selective inhibitors of SLC16A3, as well as their use in the treatment or prevention of SLC16A3-associated diseases/disorders such as cancer.

Abstract: Pneumatic simulator for an open bolt firearm including an actuator group having a stationary piston and a moving bolt. With each simulated firing cycle producing a firing event, the spring actuates moving bolt toward stationary piston such that the activator unseats a valve located in the stationary piston. Unseating the valve allows regulated compressed gas to exit a high pressure reservoir located in the firearm magazine well which drives the moving bolt back against the spring to complete a firing cycle. Subsequent firing cycles will continue automatically as long as the shooter keeps the trigger depressed. A tension rod, and laser also may comprise the simulator assembly. A nut may be used to secure the tension rod and laser. A laser cable may be used to electrically connect laser to a firing event signal generator. The firing event signal generator may include a magnet located in the moving bolt and a pickup positioned in the stationary piston.

Abstract: A shock activated laser module for simulated shooting transmits a brief laser beam to mark a point of impact. The module includes a housing, an electro-optical member, a stored energy member and a retaining cap securing the electro-optical member and stored energy member in the housing. The laser module housing is selectively attached in combination to any one of a simulated firearm barrel, a simulated firearm gas reservoir, or to an actual firearm for dry-firing practice.

Abstract: An apparatus for non-permanent conversion of a semiautomatic pistol into a compressed gas powered weapon simulator. The apparatus replaces the pistol's barrel, recoil spring and magazine with no modification of the pistol, which allows retaining the operational functions of the pistol's remaining components. Compressed gas, from the simulation magazine unit, is used in the compressed gas valve means, in the barrel unit, to operate the slide mechanism, to compress the simulation recoil spring, and to emit a laser pulse beam on a target when activated by the firing mechanism; and battery power, from the simulation magazine unit, is used to count the number of shots, lock the slide after a predetermined number of shots and transmit information from the weapon simulator to a remote data system. The compressed simulation recoil spring returns the slide mechanism back to its original position, unless locked open by the apparatus.

Abstract: A training weapon which is quickly and easilyassembled from a standard weapon without requiring any physical modification (alteration) of any component of the standard weapon. A few components of the standard weapon are removed and replaced by components of the invention. This replacement does not exceed skill level beyond a standard field-strip procedure of the particular weapon. Action of the training weapon is of the same character as the action of the standard weapon, while developing trainee's responses to the substitute firing action, and at the same time improving trainee's skill, all without the use of live ammunition. Installed components include means of cycling the the weapon's mechanism thus simulating recoil using compressed gas, optional laser pointer activating a target, and a replacement magazine including source of electricity and an electronic control circuit and operable with a gas passage unit.

Abstract: A device for measuring the entire profile of a firearm's trigger performance. This device may be either hand held or permanently mounted. The device may be connected to a sensor for sensing strike of the firing pin and connected to a computer for graphically and numerically displaying data relating to the firearm's performance. The device is capable of calculating key firearm performance parameters, including lock time and roughness of the trigger profile.
