Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A system, method, and program for managing a user key used to sign a message for a data processing system having an encryption chip are disclosed. A user is assigned a user key. In order to encrypt and send messages to a recipient(s), the messages are encrypted with the user key. The user key, in turn, is encrypted with an associated key. The associated key is further encrypted using an encryption chip key stored on the encryption chip. The encrypted messages are communicated to a recipient to validate an association of the user with the encrypted messages. The associated key is decrypted with the encryption chip key. The user key is decrypted with the associated key, and the messages are decrypted with the user key. Thereafter, validation of the association of messages with the user is removed by revoking the associated key. In a preferred embodiment, encryption resources are centralized in a server system having the encryption chip.

Abstract: A method for enticing computer users to return to an electronic commerce portal is disclosed. In response to a user registering to a merchant server for the first time, a unique number is associated with the user. Hardware information is then obtained from a computer utilized by the user. A digital certificate is generated by encrypting the unique number along with the obtained hardware information. The digital certificate is subsequently sent to the user computer for generating a unique customer number to be displayed on a web page of the user computer. On a periodic basis, the merchant server sends a master number to the user computer to be displayed on a web page of the user computer. In response to a notification of the master number matches the unique customer number on the user computer, a prize claiming process can be initiated.

Abstract: The present invention provides a method and system for securing a computer. The method includes providing a zone of authorized operation for the computer; determining if a possessor of the computer is authorized to have possession when the computer and the possessor leaves the zone of authorized operation and pass through a portal; and allowing continued access to the computer without requiring a password if the possessor is authorized. The method and system is transparent to the possessor and provides no advantage in hiding the computer from the portal. This method and system may be easily applied in a corporate environment and is particularly apt for securing mobile computer systems.
