Appl. No.:

11/777827

Tai Hoon K. Matlin - Round Lake Beach IL, US
Dipan Pravin Surati - De Plaines IL, US

International Classification:

B02C 4/32
B02C 7/14
B02C 9/04
B02C 11/08

US Classification:

241 34, 241100, 241236

Abstract:

The present invention is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for advancing at least a top sheet from a stack of paper in a tray into the cutter elements for shredding. In one embodiment, the apparatus uses a rotatable feed roller to feed paper atop the stack to the cutter elements. The feed roller moves in an alternating manner between a lowered and raised position to engage and disengage the stack when advancing the paper therethrough. Alternatively, a rotatable cam may be used. In an embodiment, the apparatus uses a rotatable drum or rotatable belt with an internal vacuum to lift paper from the stack and feed into the shredder mechanism.

Appl. No.:

11/758583

Inventors:

Daniel J. Masterson - Geneva IL, US
Dennis Gruber - Arlington Heights IL, US
Daniel Namie - Elburn IL, US
Dipan Surati - DesPlaines IL, US

International Classification:

B62B 9/08

US Classification:

188 19

Abstract:

The present invention is a manually controlled and propelled wheeled vehicle whose wheels are locked or held in place via a braking mechanism. This invention includes a proximity sensing mechanism that determines when an operator is sufficiently in control of the wheeled vehicle. Upon an operator presence being determined, the proximity sensor calls for the release of the wheel locks and or braking mechanisms. Once the operator is no longer in the proper position, the wheel locks or brakes re-engage.

International Classification:

F23Q 7/06

US Classification:

431255

Abstract:

The present invention is an apparatus that allows a torch, lantern, or candle user to ignite an actual flame electronically with the turn of a switch. Furthermore, this invention provides the means for the user to remove the flame without the need to blow it out or manually snuff the flame.

International Classification:

H02H 7/22

US Classification:

307326

Abstract:

An apparatus in an example comprises a proximity sensor and a controller. The proximity sensor serves to indicate a presence of a living object within a preselected distance of an electrically powered outlet receptacle. The controller performs a preselected control action in connection with an operation of the electrically powered outlet receptacle upon a determination the living object is within the preselected distance of the electrically powered outlet receptacle.

International Classification:

B02C 25/00

US Classification:

241 25, 241 36

Abstract:

A shredder includes a shredding mechanism and a vibration sensor configured to detect vibrations generated by the shredding mechanism. The shredder includes a controller configured to regulate operation of the shredder's motor in response to the detected vibrations. The controller may regulate operation of the shredder so as to keep the detected vibrations below a predetermined vibration level during operation of the shredder. The controller may modify operation of the shredder (e.g., turn the shredder off, conduct an autocorrect sequence, increase or decrease the shredder's speed, display an error message) in response to the detected vibrations having a predetermined characteristic (e.g., frequency and/or amplitude within a predetermined range, a characteristic that indicates a material/paper jam or misfeed). The controller may change the predetermined characteristics over the life of the shredder to account for gradual changes to the shredder's baseline vibration characteristics as components wear in and out.

International Classification:

G02B 2100
G02B 2126

US Classification:

359392

Abstract:

A machine, method and medium for implementing functions using an input device in a manner that enhances efficient operation of a mechanism capable of operating in at least two states. The functions are implemented via a convenient input device, such as a mouse. One or more specified actuators of the input device implement a given function when the mechanism is in a first state, while at least one of those actuators implements a different function when the mechanism is in a second state. In embodiments of the present invention contemplating that the mechanism is a microscope system, two states in which the microscope system is envisioned to operate are a scan state and a pause state. The scan state allows the microscope system to execute a pre-defined scan sequence, while the pause state allows the microscope system to pause from that sequence.
