Abstract: A tool having a deployable cutting blade for making an undercut in a substrate is disclosed. The tool has a chamber positioned between its cutting tip and its tang. The cutting blade is movably mounted within the chamber. The blade is movable by sliding, pivoting or deflecting on a cantilever mounting and is movable between a retracted position within the chamber and an extended position projecting outwardly to engage and cut the substrate. Actuators for moving the blade include an eccentric cam mounted on a camshaft, a push rod and an inflatable balloon. Blades are also resiliently mounted and oriented so that their engagement with the substrate will cause them to retract into the chamber when the tool rotates in one direction and deploy into the extended position when the tool rotates in the opposite direction.

Abstract: A multi-function tool includes a pair of handles and an implement slidably coupled to the handles. The implement is configured to slide in a linear fashion between a stowed position and a deployed position. A bias mechanism is coupled to the implement such that the bias mechanism biases the implement in the direction of the deployed position.

Abstract: A stuffed animal toy for children that emulates the awakening of the stuffed animal upon the user touching one of various locations upon the body of the stuffed animal thereby activating an appropriate pre-recorded audio message. The stuffed animal also includes a second head portion such as a Santa Claus-like head portion mounted within a recess behind the original teddy bear head portion that can be easily converted manually by a child from a first position representing the original teddy bear configuration, to a second position, representing a second configuration such as a Santa Claus head configuration for holiday seasons. Upon the manual exchange of the head portions of the stuffed animal, a switch is activated which enables a pre-recorded audio message to play through a speaker located within the stuffed animal. The audio message played corresponds to the head portion which appears on the stuffed animal after the exchange.

In certain aspects such a disc has a weight or weights, secondary piece or secondary disc connected to the disc body on either the top or bottom thereof, the weights(s), secondary piece or disc for facilitating flight of the disc body.

Abstract: A core retainer includes a base plate releasably attached to a concrete floor from which a concrete core is to be removed. A brake assembly atop the plate includes a plurality of brake pads for contact with the interior of the core drill bit. The retainer is configured to fit within the core drill bit and either rotate with the core drill bit or be stationary relative thereto. Upon drilling, the plate and separated core fall to the floor below. This movement is translated to the brake assembly by the linkage such that the brake pads engage the core drill bit at a sufficient pressure allowing for the separated core to be retained within the core drill bit.

Abstract: An ambulatory mechanical leg system drives a mechanical leg (100, 21) with a crank (91) to pivot about a pivot axis (102) to produce uniform rectilinear motion at the distal end (41) of the leg (100, 21) during a stride stroke (51) portion of a crank revolution or cycle and then lifts the distal end (41) to fast-return it in a step stroke (61) during the remainder of the revolution to a starting point for the next stride stroke (51). The crank (91), leg (100, 21) and pivot axis (102) sizes and proportional lengths or distances are modeled to an angular profile that produces nearly constant velocity, and mechanical structures maintain nearly rectilinear motion, of the distal end (41) of the leg (100, 21) during the stride stroke (51).

Abstract: A device for retaining a three-dimensional image includes a retainer capable of arresting displacement of pins in a position corresponding to a contour of a load applied to the pins.

Abstract: A universal chassis which may be assembled with modular componentry allowing for a play pattern with the user in which modification of the overall construction of the vehicle is encouraged. The modularity is purposely built in to allow users to modify their Battlebot chassis. In operating the configured vehicle, two motors, i.e., left and right, are provided with pulsed controlled operation to facilitate two-speed performance. The ability to transmit/receive IR signals modulated on one or more of multiple carriers facilitates the play pattern with simultaneous operation of multiple vehicles. An impact sensor or the like provides for detecting impacts, and processor control may be used for counting impacts in order to modify the functionality accorded to the user with the universal chassis.

Abstract: The present invention is a toy device that creates a visual illusion using a vibrating figure and strobe lighting. The user controls the strobe illumination frequency, as well as other potential aspects, to create different visual illusion effects.

Abstract: A jar opening aide employs a lever action for lifting a lower peripheral lip portion of a jar sealing lid, defeating the sealing of an interior of the jar, and compromising any vacuum present within the jar. The jar opening aide may be structured as an elongated member having a first end, a middle portion, and a second end. The first end includes a lid engaging portion for contacting and engaging the lower peripheral lip portion of the jar sealing lid, enabling an upward force to be applied for lifting the peripheral lip portion and defeating the seal. A user adjustable fulcrum mechanism, which is coupled to the middle portion, is adjustable by a user so that the jar opening aide may be used with jar sealing lids of differing vertical heights.

Abstract: A covered money holding tray with a series of toy money holding compartments and a cavity for receiving a book such that when the cover is closed with the book in place, the compartments are closed off, preventing the contents of the open compartments from spilling out should the tray be moved about, with the cover in a preferred embodiment being clear or translucent so that the cover or back of the book can be read when the cover is closed.

Abstract: The waterproof illuminated disc flyer is an illuminated and waterproof flying plastic disc. The disc has upper and lower disc members sealed together at the outer perimeter of the discs, and is illuminated by light-emitting diodes (LEDs). A pushbutton switch and a battery compartment are enclosed within a waterproof enclosure formed between the upper and lower discs. A battery cover having a thin depressible plastic membrane enables a user to toggle the switch from outside the waterproof interior. The upper surface of the flying disc has a centered dome having six spokes, each spoke having a LED extending from alternating opposite ends.

Abstract: An attachment structure for motor and a racing vehicle toy, wherein a motor can easily be inserted and removed therefrom, are provided. The attachment structure includes a motor holding plate capable of turning on a predetermined rotational shaft line attached to a chassis or base body.
