Title: Determining an initial estimate of a result value of a reciprocal operation
Inventor: LUTZ DAVID RAYMOND
IPC: G06F7/544
Filed: 2005-07-25
Abstract: The present invention provides a data processing apparatus and method for generating an initial estimate of a result value that would be produced by performing a reciprocal operation on an input value. The input value and the result value are either fixed point values or floating point values. The data processing apparatus comprises processing logic for executing instructions to perform data processing operations on data, and a lookup table referenced by the processing logic during generation of the initial estimate of the result value. The processing logic is responsive to an estimate instruction to reference the lookup table to generate, dependent on a modified input value that is within a predetermined range of values, a table output value. For a particular modified input value, the same table output value is generated irrespective of whether the input value is a fixed point value or a floating point value. The initial estimate of the result value is then derivable from the table output value. This provides a particularly efficient technique for performing the initial estimate generation within a data processing apparatus where the reciprocal operation may be performed on either fixed point values or floating point values.

Title: Exerciser with elliptical and stepping functions
Inventor: HONG CHOU
IPC: A63B23/04
Filed: 2005-12-30
Abstract: The present invention discloses a fitness machine with elliptical and stepping functions for integrating a stepping exercise and an elliptic exercise for exercising users' legs as well as a swing exercise for exercising users' arms. The fitness machine comprises a frame, two sliding rods 3, two pedals 32, and two support rods 5. If the two support rods 5 are fixed to the frame, the two pedals 32 will be limited such that the two pedals 32 produce an up-and-down stepping exercise. If the two support rods 5 are fixed to the sliding rods 5, then the limiting effect of the pedals 32 provided by the support rods 5 will be diminished, so that the two pedals 32 produce a back-and-forth elliptic exercise (see figure 6). Regardless of the stepping exercise or the elliptic exercise, the two swinging arms 4 are linked by the two sliding rods 3 and swung back and forth, so as to provide both exercisers for legs and arms.

Title: System for enabling DRM multi-session recording onto a recordable medium
Inventor: KURIHARA SHINICHI
IPC: H04N5/765
Filed: 2008-02-06
Abstract: The system includes a content distribution centre which holds a plurality of items of encrypted content data and a plurality of respective keys suitable for decrypting the content data, a terminal device on which the recordable medium (e.g. a CD or DVD) is loaded and a communication link connecting the content distribution centre and the terminal device. A first session is initiated by the terminal device sending both medium information and a request for first content to the content distribution centre, the content distribution centre extracts the encrypted first content corresponding to the request, encrypts its respective first content key using at least the received medium information to form a first session encryption key and sends this, together with the encrypted first content to the terminal device, which records the encrypted first content onto the recordable medium. A second session is initiated by the terminal device sending the medium information, a request for secondary content and the first session encryption key to the terminal device, the content distribution centre decrypts the first session encryption key using at least the medium information to produce the first content key, extracts secondary encrypted content corresponding to the request for secondary content, decrypts this using its respective secondary content key, re-encrypts the secondary content using the recently extracted first content key and sends the resulting encrypted content to the terminal device, which records the encrypted secondary content onto the recordable medium. The medium information may be associated with the recordable medium on which the first and second content is stored, or it may be associated with a separate recordable medium (such as an SD card) also loaded onto the terminal device. Thus multi-session recordings can be decrypted using a single encrypted content key, rather than using a separate key for each session.
