Title: Touch sensitive device
Inventor: HARRIS NEIL JOHN
IPC: G06F3/041
Filed: 2010-04-01
Abstract: A touch sensitive device comprising a touch surface, a force exciter coupled to the touch surface to excite vibration in the surface in response to a signal sent to the exciter, with the touch surface and exciter together forming a coupled system and a signal generator to generate the signal, with the signal generator generating a carrier wave signal at frequencies within the fre-quency bandwidth of the coupled system and modulating the carrier wave signal with a complex modulation where the modulated carrier wave signal has a time response comparable to that of a low frequency signal which produces a desired haptic sensation whereby a user touching the touch surface excited by the exciter in response to the modulated carrier wave signal experiences the desired haptic sensation which is perceived at a frequency below the frequency bandwidth of the coupled system.

Patent CA-2758710-A1 (CA)
Inventor: BONAC MARTIN
IPC: G11B27/10
Filed: 2011-11-07
Abstract: Cadence of body motion is derived from the measurement of acceleration over a sample period by a sensor incorporated in a portable electronic device. The measurement is transformed to obtain amplitude versus frequency information over a range of frequencies.  The maximum amplitude frequency is determined and higher sub-ranges are created, each based on the peak found in the previous range. To each range a low end cut-off value is applied to the amplitude. The maximum amplitude frequency of the last range is treated as cadence value.

Abstract: The subject invention provides for a feedback loop system and method that facilitate classifying items in connection with spam prevention in server and/or client- based architectures. The invention makes uses of a machine-learning approach as applied to spam filters, and in particular, randomly samples incoming email messages so that examples of both legitimate and junk/spam mail are obtained to generate sets of training data. Users which are identified as spam-fighters are asked to vote on whether a selection of their incoming email messages is individually either legitimate mail or junk mail. A database stores the properties for each mail and voting transaction such as user information, message properties and content summary, and polling results for each message to generate training data for machine learning systems. The machine learning systems facilitate creating improved spam filter(s) that are trained to recognize both legitimate mail and spam mail and to distinguish between them.
