    • Apparatus (10) and a method for rendering a weapon (12) incapable of use unless authorized by a specified individual. More than one person may be authorized to use the weapon, however only one person may be authorized to use it at any one time. Each authorized person carries a badge (14) or other device which includes an rf transmitter (TAU) capable of transmitting a coded signal to a receiver (REU) installed in the weapon in response to a coded query from a unit (EU) installed in the weapon. If a properly coded transmission is received by the weapon, it becomes capable of being fired by the person who authorized its use. However, the weapon will not fire unless the person using the weapon is also standing behind the weapon. This prevents the weapon from being turned on the person authorized to use it. The apparatus stores details of the weapon's use (e.g., who, when, and where). This information is released upon receipt of an authorized code.

    • A method for controlling the current profile for current supplied to each phase of a poly-phase switched reluctance motor when a respective phase of the motor is active. The interval each motor phase is active is determined as a function of motor operating conditions, as is a desired profile of current flow into and out of a phase winding (W) associated with the phase. The current profile has an initial portion (Z1) in which current flows into the winding from an initial value current value to a peak current value (I.sub.p). It also has a terminal portion (Z3) including current cut-off to the winding with current in the winding being either stored or dissipated prior to the phase becoming inactive. There may also be an intermediate portion (Z2) occurring between attainment of the peak current and the beginning of the terminal portion of the current profile. Current flow to the winding starts at the beginning of the initial portion of the phase, and current flow to the phase winding is cut-off prior to the end of the phase. Termination of current flow to the phase winding normally causes ringing in the motor because of the abrupt transition in current flow which occurs at current cut-off. However, according to the invention, current flow to the phase winding is now controlled throughout the active portion of the phase in accordance with the predetermined current profile. This includes determining the slope of current ramp-up during the initial portion of the profile until the peak current level is achieved; and, curvature of the current profile subsequent to cut-off of current flow to the phase winding. The current profile is controlled such that the slope of curvature of the profile immediately prior to current cut-off corresponds to the slope thereof immediately after cut-off. As a result, there is no transition in the current profile at current cut-off, and no ringing is produced in the motor by terminating current flow to the phase winding.

    • Apparatus (10) for launching spherical and disc-shaped objects (O) used in the practice or play of a sport. A launcher assembly (12) includes a constantly rotating arm (14) rotatable about a center pivot (P). An object to be launched is loaded into an inlet end (16) of the arm adjacent the pivot for the object to be drawn outwardly by centrifugal force toward an outer end (18) of the arm from which the object is released. The velocity of the object when it is launched is a function of the length of the arm and the speed at which the arm is rotating. A feed assembly (20) holds a number of homogeneous objects. A feed mechanism (100) of the feed assembly is selectively operable to feed the objects into the inlet end of the arm. A control panel (148) enables a user to remotely control operation of the apparatus, to control individual launches, or to preset an interval at which objects are automatically launched. A drive unit (24) includes a motor (26,26') for constantly rotating the arm. The motor's speed is controllable to rotate the arm over a range of speeds so to control the velocity of the object when it is launched.
    • 用于发射用于实践或玩运动的球形和圆盘形物体(O)的装置(10)。 发射器组件(12)包括绕中心枢轴(P)旋转的不断旋转的臂(14)。 要发射的物体被装载到靠近枢轴的臂的入口端(16)中,用于通过离心力向外拉动的物体朝向从其释放物体的臂的外端(18)。 物体发射时的速度是手臂长度和手臂转动速度的函数。 进料组件(20)容纳多个均匀的物体。 进料组件的进料机构(100)可选择性地可操作以将物体输送到臂的入口端。 控制面板(148)使得用户能够远程控制设备的操作,控制单独的启动,或者预设对象自动启动的间隔。 驱动单元(24)包括用于不断旋转臂的马达(26,26')。 电机的速度是可控制的,以在一定范围的速度上旋转手臂,以便在发射物体时控制物体的速度。
