Abstract: A toy assembly; the toy assembly includes a stake and a receptacle. The receptacle is a bag which removably houses at least one pet toy. The toy assembly is capable of entertaining pets, particularly dogs, and provides a way for dogs to play by themselves if an owner/caretaker cannot play at a given time.

Abstract: A combination cigarette lighter and eye-drop applicator wherein the eye-drop device is secured to the lighter by being press fit secured with plastic clips or secured by hollow housing, a reservoir in the housing adapted to hold a supply of eye-drops and a squeeze bottle for applying the eye-drops in addition to the fire-lighting section of ordinary lighters, such that a person could ease eye irritation and redness due to smoke or allergies without needing anything but a lighter.

Abstract: A secure method for sending register, authenticated electronic documents is disclosed. The sender sends a first set of data, not including the plaintext message, encrypted with the public key of the recipient, and a second set of data, including the plaintext message, encrypted with a session key which was included in the encrypted first set of data. The recipient is first asked if he wants to receive the message, and then, upon seeing an abstract, asked if he wants to receive the full message. Confirmatory data regarding the decryption of the message and the presentation of the data to the recipient is recorded and sent to an authentication agent.

Abstract: A secure method for sending registered, authenticated electronic documents. The invention validates sender and recipient identities, provides for non-repudiation of authenticated documents by sender and recipient, provides an evidence trail, and protects the integrity of the document. The invention is constructed so that a sender can be supplied with proof that the intended recipient received and opened an authenticated document. A neutral third party acts as a document registration agent, and witness to the transmission and receipt of the authenticated document. In the event of a dispute between sender and recipient, the third party can provide an irrefutable record of the contents of the document and of the history of the transmission and receipt of the document Because the third party never has possession of the electronic document, the method provides maximum privacy for sender and recipient. The method is readily adaptable to both key recovery and key escrow.

Abstract: A portable Personal Identification Card allows a cardholder to enter a PIN code into his card at a location remote from an authorization terminal. In an alternate embodiment, a PIN code may be entered at the authorization terminal. The authorization terminal reads the cardholder's account number from the PIN card. The account number is transmitted to a central computer which uses this number to index into memory to find a personal identification number and encryption parameters. The central computer transmits a pseudo-random number to the PIN Card. Both the PIN Card and the central computer perform an encryption of a function of the corresponding personal identification number and pseudo-random number to derive a CGIPIN (Computer Generated Image of the PIN). If the CGIPIN transmitted from the PIN card matches the CGIPIN of the central computer, access is authorized.

Abstract: A domain-based encryption system which uses identical domains known only to the parties involved in the communication. An encrypted message is sent between communicating parties which consists of a stream of coordinates which locate specific points in the domains. The located points comprise a symbol set that forms the plaintext message.

Abstract: A pet watch process and circuit discloses the use of an animal carried timer that gives audio signal after a preset time has elapsed. The timer is used in conjunction with a conditioning program to produce a desired motive behavior, e.g., to induce an animal to come home when the audio signal sounds. The timer is incremently adjustable and has a liquid crystal display. The conditioning method is an incremental process which begins with the owner calling the pet and sounding the alarm simultaneously with the pet in the same room, after longer and longer incremental time intervals, and finally is set off with the pet remote from its owner. (i.e. outside the house) As the training process proceeds, the alarm is set off.
