A laptop computer system includes a protected mode microprocessor capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. When running a multi-tasking operating system where an application program is being executed in a restricted mode, a suspend/resume operation can be carried out in which the system is substantially powered down and then powered back up, and will resume the interrupted application with the restricted mode back in effect. Further, set-up changes such as adjustment of the processor speed can be made without exiting the application program running in the restricted mode.

Suspend/resume capability for a protected mode microprocesser

A prisoner control harness has a retractor reel with a cord leading to a cuff worn at one of the prisoner's extremities. Engageable ratchet means are provided for limiting the motion of the retractor reel and remote control means under the control of a custodian or guard, are provided for activating the ratchet so that if the custodian needs to disable the prisoner, a signal from the remote control activates the ratchet so that the cord reels in but will not reel out, limiting the prisoner's ability to escape.

Interrupt for a protected mode microprocessor which facilitates

A laptop computer system includes a protected mode microprocessor capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. The system includes a first interrupt mask register having a bit for indicating whether an interrupt is to be recognized by the processor, a second interrupt mask register having a bit for indicating whether the interrupt is to be recognized by a further circuit, and an arrangement responsive to a load of the first mask register for conforming the bit of the second mask register to the bit of the first mask register in a manner invisible to an application program being executed by the processor.

Apparatus for maintaining one interrupt mask register in conformity with

A radio receiver and its power supply are included in a circuit with a switch which is responsive to introduction of a force field, such as a magnetic field. When the field is activated, as by the introduction of a sufficiently powerful magnet, the switch is opened and the radio receiver is deactivated. Removal of the force field automatically restores the radio receiver to operable condition.

A laser beam generating module is disposed at or near the butt end of a handgun in substantial alignment with the gun barrel. The module may optionally include means for activating the laser which are responsive to the horizontal or vertical attitude of the handgun, means for adjusting the aiming module for accuracy at various ranges, and means for suppressing the laser beam until the user of the handgun is ready to use it. A version of the invention places the laser module at the end of a magazine insertable into the handgrip of an automatic handgun so that the laser module is carried just adjacent the butt end of the handgun. Placement of the laser module at the butt end of the weapon yields accuracy adequate for routine police work, does not upset the balance and feel of the weapon, and it enables the weapon to be carried by its user in its conventional holster. Variations of the invention are described such that the laser module is built into the handgrip of the weapon, inserted when attached to a conventional ammunition clip, and attached to the butt end of the weapon by means of a mounting bracket.

Restraint apparatus for prisoners is worn beneath ordinary clothing so as to be unseen by the general public, in order that the prisoner's presumption of innocence not be denigrated by public display as is the case with manacles or the like. The apparatus operates by remote activation of an effective but nonlethal impact, such as a brief electrical interference with the somatic nervous system, or discharge of a small dose of tear gas or mace into the prisoner's breathing space.
