摘要:
Handwriting recognition which is invariant with respect to translation, rotation and scale is achieved with a new feature signal, ratio of tangents, and a new application of the normalized curvature feature. Use of these features is optimized by augmenting the ratio of tangents with the sign of local curvature and weighing each feature signal with its relative discriminative power.
摘要:
A method of handwriting recognition is provided that combines the efficiency of a point oriented system and the shape information of a segment oriented system in an HMM based handwriting recognition system. The partial segmentation hypotheses obtained using the point oriented features in a conventional Viterbi search are augmented with scores based on segmental shape measurements made on the hypothesized segments. In addition, a method for segmentation of a handwriting sample is accomplished by incorporating a feature to distinguish between continuous and not continuous strokes and influencing the indicated hypothesis score by adding a penalty to the contraindicated hypothesis score.

摘要:
Methods and systems for performing handwriting recognition which include, in part, application of stochastic modeling techniques in conjunction with language modeling. Handwriting recognition is performed on a received data set, which is representative of a handwriting sample comprised of one or more symbols. Recognition is performed by selectively segmenting the data set into one or more strokes utilizing an evolution grammar for identifying each one of the strokes among one or more alternatives. Each one of the strokes represents a segment of the handwriting sample. The identified strokes are evaluated as a stroke sequence, representative of one or more of the handwriting sample's symbols, to identify the handwriting sample.
摘要:
A method for differentiated access control on a computing device having a connection with a second device, the method checking whether a timer has expired on the second device or if a connection is lost to the second device; and preventing at least one of the plurality of application subsets from being launched or enabled if the timer has expired on the second device or the connection is lost to the second device.
摘要:
A method of providing a password to a handheld electronic device having a reduced keyboard and a non-predictive keystroke interpretation system, wherein the reduced keyboard is of a particular keyboard type and the non-predictive keystroke interpretation system is of a particular system type. The method includes receiving a first character string in an electronic device, such as, without limitation, a PC, that is separate from the handheld electronic device, generating one or more second character strings in the electronic device based on the particular keyboard type, the first character string, and, possibly, the particular system type, and transmitting the one or more second character strings from the electronic device to the handheld electronic device as the password.
摘要:
A system and method for retrieving certificates and/or verifying the revocation status of certificates. In one embodiment, when a user opens a digitally signed message, a certificate that is required to verify the digital signature on the message may be automatically retrieved if it is not stored on the user's computing device (e.g. a mobile device), eliminating the need for users to initiate the task manually. Verification of the digital signature may also be automatically performed by the application after the certificate is retrieved. Verification of the revocation status of a certificate may also be automatically performed if it is determined that the time that has elapsed since the status was last updated exceeds a pre-specified limit.
摘要:
A system and method for controlling data communications between a server and a client device, such as a mobile device. Embodiments relate generally to a technique where stop data is provided to the client device. This stop data can be transmitted (e.g. by the client device) to the server. When processed by the server, the stop data indicates to the server that at least some of the encrypted data received by the client device from the server was not decrypted using the second key (e.g. as may be the case when the second key has been deleted). Upon receiving the stop data, the server may, for example, withhold the transmission of data encrypted with the first key to the client device until the second key is restored on the client device. In one embodiment, the stop data is provided to the client device in an encoded (e.g. encrypted) form.
摘要:
Systems and methods for processing encoded messages within a wireless communication system. A server within the wireless communication system provides one or more indications to a mobile device as to certain conditions existing with respect to an encoded message. The mobile device performs a different message processing function based upon whether the indication is provided. The indications may include indicating whether a message exceeds a message size threshold and/or may indicate whether a partial message is being sent.

A displayed string of emails is effectively compressed for improved readability by deleting some or all headers and/or by skipping the cursor from one message body to another in response to hot key actuation(s) by a user.
