A mouse (20) comprises first (24) and second (28) projections on the bottom surface of the mouse housing. The second projections (28) only come into contact with the mouse mat on application of pressure by the user, so as to assist in holding the mouse still, for example during double clicking operations.

In a mouse connected to a personal computer, a casing body is provided with a space for housing a data storage medium therein. A data processor communicates data between the personal computer and the data storage medium housed in the casing body. A door member covers an opening formed on the casing body, through which the data storage medium is attached or detached, in a closed position thereof. The door member constitutes a part of an outer face of the casing body at the closed position thereof...

A mouse for a computer has a small touch panel to realize improved functions. The mouse (40) has a lower case (41) and an upper case (42) that covers an upper part of the lower case. A front part of the upper case has an integrated support. The touch panel is installed on the support, and a key top (43) is fitted to the upper case to fix the touch panel. An instruction is generated according to a finger touching period or the movement of a finger on the touch panel, and the instruction is transm...

A position control system employing a movable detector means which communicates energy to and from a pattern of passive, position-related indicia or marks on a surface. In the preferred embodiment the movable detector means includes a light source and a four-quadrant detector, with the surface having a high contrast checkerboard square pattern. The four-quadrant detector will report different states as the detector means is moved across different squares. The states are decoded in a lookup table...

A mouse trap includes first and second telescopically related housing members which are movable between extended and retracted positions. A door opening is provided in one of the housing members which provides access to the interior of the housing when the housing is in its extended position but which is blocked by the other housing member when the housing is in its retracted position. A spring biased striker arm is mounted within the housing members and is adapted to be held in a cocked positio...

The present invention relates to mouse traps, consisting of a first means that employs a spring type striker that is held down by a rod or lever, and a second means that employs a prop to hold up a inverted box or container. The present invention employs the two well known means previously stated to produce a nearly inescapeable mouse trap, the spring type mouse trap that employs a rod or hold down lever to restrain a striker, is placed under a propped up inverted box or container, the spring tr...

An animal trap of the type which precipitates an animal into a disposal chamber (12) through a disposal opening (40), characterized by having a pyramidal bait chamber (11), with an entrance (32) and non-grip internal surfaces, around the disposal opening (40), and a pivoted shutter (42) that normally closes the disposal opening (40), but is actuated by the weight of the animal to not only unclose the disposal opening (40), but also close the entrance (32).

A mouse comprises a cover and a displacement pad which is displaced upon movement of the mouse over a surface. Displacement transducer means, e.g., strain gauges mounted in a parallel arm linkage, are used to ascertain direction of motion. Noise created by sliding motion is monitored by a microphone, the output of which is a function of velocity and therefore distance. The microphone may be mounted to the displacement pad, and the pad and microphone covered with a friction and vibration enhancin...

In the analysis of liquids, particularly biological liquids such as serum or urine, mouse serum or a component of mouse serum is used as a reagent. The reagent has the ability to combine with antibody:antigen complexes (but not free antibody or antigen) and to combine with IgG and IgM. It differs markedly from human C1q in that it remains active at high pH and in the presence of certain substances known to destroy human C1q. It is a very broadly applicable reagent in immunoassays, and particular...

The trap has a ring shaped passage with a door which, when opened, extends into the passage so that a mouse can only enter the passage in one direction. A bait trail in the passage extends around to the back side of the door where it can be pushed closed by a mouse, or released by the mouse and closed by a spring. Magnetic or spring means are disclosed for holding the door in the closed position. An attractant dispenser is provided for dispensing fresh attractant near the back side of the door w...
