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 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 pseudorandom 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.

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.
