Title: Data relay device and routing method
Inventor: AOKI AKI
IPC: H04L12/56
Filed: 2007-11-13
Abstract: A data relay device (10) previously stores in a total cost storing section (81) the total cost of nodes of each of a plurality of different routes from a local device to a data relay device (90). When establishing a path with a prescribed band to the data relay device (90), a route is selected on the basis of the total cost and directs data to the selected route for transmission. For routing, the data relay device (10) forms a group of routes in which the total cost difference of each route falls within a prescribed value and selects a route with the number corresponding to the band of the path from the same group of the formed group. When the prescribed value is the same value as a differential delay tolerance set in the data relay device (90), a path between the data relay device (10) and the data relay device (90) can be established without generating a differential delay alarm.

Title: Providing an time delayed and pitched shifted accompaniment to a sound produced by a user
Inventor: KEATING DAVID
IPC: A63H3/28
Filed: 2012-01-30
Abstract: A method and apparatus for providing an accompaniment to a sound produced by a user is described. The method comprises generating an electrical output signal from a sound produced by a user, preferably using a microphone 2. A time delay and a shift in the pitch is introduced to the electrical output signal before an audio output is generated. The time delay may be variable, in the range of 38 ms to 140 ms, and may reduce with an increase in amplitude of the electrical output signal. The pitch shift may involve shifting the pitch up an octave, by identifying the fundamental frequency or cycle time of the electrical output signal and transmitting a sample of the cycle time at twice the sample rate. The described method can be incorporated within a novelty soft toy 1, such as a doll or animal, so that it appears to sing a highly realistic duet with the user. An audio speaker may be incorporated into the soft toy 1.
