Abstract: An electrical connector cleaning devices includes a first elongate cleaning element extending outwardly from a housing, wherein the first cleaning element includes raised surface portions extending radially outward from its outside wall surface. A second elongate cleaning element extends outwardly from the housing and includes raised surface portions extending radially inward from its inside wall surface. Each of the first and second cleaning elements is a cylindrical tube having a longitudinally extending open seam forming a gap for permitting a flexing of the cleaning element walls through a biasing force placed thereon. Each of the raised surface portions forms rings extending around the inside and outside wall surfaces of the first and second cleaning elements, respectively. One ring has its raised surface portions angularly offset along the longitudinal direction from an adjacent raised surface portion in an adjacent ring of raised surface portions.

Abstract: A device is capable of locking or unlocking a card in a card reader. An actuator carries a drive bushing onto which one end of a coil spring is mounted such that the axis of the coil spring is approximately parallel to the rotation axis of the actuator. The opposite end of the coil spring is mounted on a drive nut. A threaded shaft is fixed to a slide block with an elongated hole, and the movements of both are constrained to a single degree of freedom by the engagement of the elongated hole with a fixed pin and by the engagement of an extension of the threaded shaft with the inner hole of the drive bushing. The linear movement of the slide block causes a latch plate to move by means of a linear sliding pair between them so as to lock or unlock the inserted card.

Abstract: Disclosed is a printer having: a fixed chassis mounted thereon; a moving chassis being engageable with the fixed chassis between an open position and a closed position; a cutter including a fixed blade and a moving blade; a paper drive roll; a thermal head; and driving means driving the paper drive roll to subject paper rolling along a paper path formed between the thermal head and the paper drive roll, and the fixed blade and moving blade; wherein the thermal head is in a path of the paper drive roll and wherein the moving blade urges the fixed blade towards the fixed chassis when the moving chassis is at the closed position, and a restraining module for maintaining an appropriate gap between the fixed blade and the moving blade when the moving chassis is engaging the fixed chassis.

Abstract: Disclosed is a printer including: a fixed chassis mounted on the printer; a moving chassis being engageable with the fixed chassis between an open position and a closed position; and a cutting mode switching module for controlling a cutting mode of the printer, characterized in the cutting mode switching module comprising: a fixed blade mounted at the fixed chassis; a moving blade having an elongated pivot hole, through which pivot hole the moving blade is pivoted to a pivot end of the moving chassis such that the moving blade is shiftable within the pivot hole between a first position and a second position, and such that the fixed blade and moving blade is formed with a paper path therebetween when the moving chassis is at the closed position; a motor mounted in the moving chassis; and a crank pin engaging with and cranking the moving blade and driven by the motor to rotate in a first direction or a second direction; whereby when the moving chassis is at the closed position, the moving blade is capable of pe

Abstract: The unauthorized separation of a second member such as a door with respect to a first member affixed to a computer frame and the subsequent replacement of the initial position of the door creates a change of state of a square loop magnetic member integral with the computer frame. This change of state can be monitored from time to time to indicate an unauthorized opening of the door.

Abstract: An electromechanical needle bar engaging device having a latch release member normally urged by biasing means into engagement with a coupling member, to unlatch the coupling member from a needle bar drive member. The latch release member sewing machine frame supports a solenoid adjacent the latch release member, which, when activated, rotates a lever supported on the latch release member, into the path of motion of the needle bar drive member. Movement of the needle bar drive member against the lever will move the lever and the latch release member on which it is supported out of engagement with the coupling member to permit the coupling member to relatch itself with the needle bar drive member. Means are provided utilizing the solenoid as an electromagnet to retain the latch release member out of engagement with the coupling member.

Abstract: The permeability and resistivity of metal sheets including those installed in enclosing structures, are nondestructively determined by injecting a unit-step pulse of current into an exposed surface of the sheet and measuring the surface voltage gradient between a pair of contacts located between the current injection contacts. The permeability and resistivity of the metal determines the rate of diffusion of current into the surface and therefore the rate of decrease of this surface voltage gradient. At steady-state the current density will be uniform throughout the thickness of the sheet resulting in the surface voltage gradient stabilizing at a value depending on the resistivity and thickness of the metal.
