A method for distributing a secret key from a key holder H to intended group members M. The method assumes that during the distribution process each party, a group member M and the key holder H, can decrypt and encrypt exchanged information such that the encrypter knows that the decrypter will be the intended party. The method preferably uses a public key / private key encryption technique in which, for example, a trusted Certificate Authority in a public key infrastructure signs the certificates to provide the public keys involved in the encryption. Alternatively, the method, together with a symmetric cipher, uses a shared secret, established in an authenticated mechanism that is outside the information exchanges of the invention. Additionally, the method uses a strong mixing function that takes several items of data as input and produces a pseudo-random authentication (or digest). Inputs to the mixing function include identity stamps that are generated by each member M and key holder H. These inputs can be the identity of the stamp generator, such as a network address, port, or protocol, a timestamp, and / or a secret value that is known only to the stamp generator. The stamps include information to bind member M if generated by key holder H, and to bind key holder H if generated by member M. Consequently, the invention authenticates each communication exchange between member M and key holder H.

The present invention is a hand held portable remote such as a key fob that allows a user to interact with the security system using a flat panel touch-pad. The touch-pad input allows a user to rapidly select and control a large number of security functions, such as Arm, Disarm, Panic, garage door open, lamp on / off, and lamp dimming control, etc. The security device comprises a housing, a wireless communication port for interface with the security system, a touch-pad input device, and processing circuitry. In order to operate the security device, the user generates a user input by creating a contact motion on the touch-pad input device with a fingertip. The contact motion may consist of a swiping motion, a tapping, or a circular motion. In order to distinguish the contact motion clearly, when the fingertip contact comprises a wider than normal contact, it causes the processing circuitry to not generate an output signal. The security device also comprises an LCD display for displaying alpha numeric control options to a user and LED indicators for indicating the modes of the processing circuitry.

The present invention relates to a music identification / purchasing system, specifically to a method for marking the time and the name of the radio station in portable device such as a key holder, watch, cellular phone, beeper or the like which will allow the user to learn via internet or regular telephone the name of the song, artist and / or music company by matching the stored data with broadcast archive. The system will allow for purchase of the full length of the identified music item or related music. An alternate embodiment provides the listener with convenient means to record a segment of the music in which he / she is interested. The recorded music segment is played back into an apparatus which can identify the song based on the play back and provide the user with information on the identified song such as title, singer or artist, composer, producer, etc., and provide related purchasing information. The user can make selections and provide payment data to the music identification / purchasing system which will result in the selections being delivered to the user by mail.

A security device which is a hand held portable remote device such as a key fob that allows a user to interact with a security system using a single button. The security system functions such as arming, disarming, panic, garage door open, lamp on / off, and lamp dimming control will be displayed by the security device as control options and will be selected by a user using a forward, backward, left or right tilting motion and depressing the power on / select button. Once a control option has been selected, the security device will transmit the control option to the security system. The security device has a portable housing, a wireless communication port for interface with a security system, a display panel, an accelerometer device, and processing circuitry. The accelerometer device is used to determine the tilt of the security device and provide a control signal related to the tilt. The security device also has an infrared communication port for downloading control options, and single push button, for turning the security device on and for initiating the transmission of the output signal.

A device and method for a key fob. The key fob device can include a housing, a lid defining one or more apertures, a circuit board including one or more switches, and a flexible film coupled to the housing and / or the lid. The flexible film can include one or more contact surfaces and stylized graphics.

The present invention is directed to a power tool including a wireless remote stop for terminating the flow of electricity to an electric motor. The electric motor is configured for operating a working element assembly of a power tool, such as an arbor / circular saw blade included a table saw. In an embodiment, a remote stop is a hand-held fob, having a housing and a button. Alternatively, the remote stop may be implemented as a foot pedal apparatus, for being disposed on a shop floor.

Methods and systems for providing a secure SSL certificate escrow service comprise: providing a secure upload webpage for a private key holder to upload an encrypted copy of a private key; receiving the encrypted copy of the private key from the private key holder via the secure upload webpage; storing the encrypted copy of the private key in memory; providing a secure decryption webpage for the private key holder to enable the private key escrow service to decrypt the private key; receiving an instruction to decrypt the private key from the private key holder through the secure decryption webpage; and decrypting the private key in response to the instruction to decrypt the private key.

This invention relates to an integrated automatic device for training and feeding a pet, which also functions as a play mate while the owner is absent or otherwise engaged. A toy holder, when actuated by an ejector, throws a toy placed therein to a predetermined distance. This toy holder is actuated by a spring connected to a spring tensioner and a rotating shaft activated by a motor programmed by microprocessors. Voice command issuer and proximity switches are provided to regulate the functioning of the device. The device is connectable to a pet feeder including a feeder capable of supplying feed for a predetermined period. The entire system is controllable by a remote control.

A token generator such as a keyfob is used to access the computer of an authentication entity different from the authentication entity that issued the token generator. The token generator stores authentication entity identification information identifying the authentication entity that issued the token generator. The token generator causes a user computer to transmit an authentication request including such authentication entity identification information together with a token generated in synchronization with the authentication entity issuing the token generator, so that the authentication request can be routed to the appropriate authentication entity that issued the keyfob for validation. The authentication request can be sent directly to the authentication entity that issued the token generator. The authentication request can also be sent to the authentication entity that issued the token generator via another authentication entity to which the user computer attempts to access.
