Abstract: A system made up of a portable information terminal mountable on a shopping cart for providing product and advertising information while the cart is moved inside a store and an external memory device connectable to the portable information terminal, the external memory device including a memory housing, a non-volatile memory storing data in the memory housing, and a first electrical connector projecting from the housing for allowing a processor to access the stored data; the portable terminal including a terminal housing including a display, a processor in the terminal housing for causing the display to display product information and advertisements, and a second electrical connector inside the housing complementary to the first electrical connector for connecting an external memory device to the processor, the terminal housing including a passage providing access to the second electrical connector from outside the terminal housing and at least one door recessed in the passage shiftable from a first position

Abstract: A building structure with a tubular frame structure in a hut shape may be provided with cladding in the form of curved panels to provide a temporary or emergency shelter. These panels may consist of two spaced-apart plastic sheets fused together by parallel ribs serving as webs to provide parallel channels therein, e.g., Coroplast™-like sheeting. Such sheeting is preferably stiffening with one or more battens that are inserted through the hollow channels of the panel allowing them to be used as semi-rigid cladding over the entire building structure. The outer tubular members of the frame are all curved to improve rigidity. The frame includes channels for seating the panels as well as contribute to the structural integrity of the shelter.

Abstract: The distance between the clamps at opposed ends of a shoulder rest bridge adjustable in infinitely fine increments by utilizing a pressure plate which, in an engaged mode, presses a brake member made from an elastomer, particularly soft rubber, against the underside of the bridge body. The pressure plate is actuated by a pivotable latch having a lever and co-operating with a non-rotatable bearing member having a ramp surface complementary in the direction of incline and in pitch with the ramp surface of the pivotable latch. A supplementary camming mechanism provides, upon hand displacement of one of the clamps towards the other into engagement by both with the instrument, an additional motion of the one clamp toward the instrument thus increasing the clamping force holding the shoulder rest to an instrument.
