Abstract: A computer-implemented system and method to manage the communication of a user are disclosed. In one embodiment, when a person tries to electronically convey a message to the user, the status of the user, the identity of the person, and the urgency of the message can be identified. The access priority of the person can be determined based on the person's identity. Then, the message can be managed using one or more rules and in view of the status of the user, the access priority of the person and the urgency of the message.

Abstract: A number of embodiments regarding computer-implemented systems and methods to manage electronic communications are disclosed. In one embodiment, an apparatus, using at least a network-based portal based on Internet protocol, provides different communication modes to a first user, with messages eligible to be received by a second user based on any of the modes, depending on an identifier associated with the second user; and receives an indication from the first user to select a communication mode for a message for the second user. In the embodiment, the apparatus could receive contact information associated with the second user to allow the second user to participate, with the contact information not provided to the first user even when the message is received by the second user, and with the contact information being distinct from the identifier.

Abstract: Computer-implemented systems and methods to manage electronic communications are disclosed. In one embodiment, an apparatus, using at least a network-based portal based on Internet protocol, receives a message with a user identifier from a person's wireless device; receives a communication option from the person based on options provided to the person, with all the options using the user identifier, in view of the portal being based on the Internet protocol; permits the user to block the person from accessing the user; enables the message to be received by the user if the person is not blocked by the user; and determines user availability to receive the message. In the embodiment, the apparatus requires user contact information for the user to receive messages, with the user contact information not provided to the person, and with the user contact information being distinct from the user identifier.

Abstract: Methods and systems to produce audio output signals from audio input signals. In one embodiment, a first portion of the audio input signals can be pre-processed, with the output used to modulate ultrasonic carrier signals, thereby producing modulated ultrasonic signals. The modulated ultrasonic signals can be transformed into a first portion of the audio output signals, which is directional. Based on a second portion of the audio input signals, a standard audio speaker can output a second portion of the audio output signals. Another embodiment further produces distortion compensated signals based on the pre-processed signals. The distortion compensated signals can be subtracted from the second portion of the audio input signals to generate inputs for the standard audio speaker to output the second portion of the audio output signals. In yet another embodiment, noise can be added during pre-processing of the first portion of the audio input signals.

Abstract: A hearing enhancement system that enhances a user's hearing is disclosed. For example, the system can include an interface unit that has a directional speaker and a microphone. The microphone captures input audio signals that are transformed into ultrasonic signals. The speaker transmits the ultrasonic signals, which are transformed into output audio signals by interaction with air. At least a portion of the output audio signals are modified to enhance the hearing of the user. Based on the system, the user's ear remains free from any inserted objects and thus is free from annoying occlusion effects. Compared to existing hearing aids, the system is relatively inexpensive. In another embodiment, the system can also be used as a phone. In yet another embodiment, the system can also access audio signals from other portable or non-portable instruments, wired or wirelessly, such as from home entertainment units, phones, microphones at a conference or speakers at a movie theater.

Abstract: A wireless communication system based on a directional speaker is disclosed. The system can include an interface unit and a base unit. The audio signals from the speaker can be generated by transforming ultrasonic signals in air. This allows the production of directional audio signals even when the aperture of the speaker has dimensions in the order of a few centimeters. The audio signals from the speaker can be heard hands-free. Further, privacy protection is enhanced. In one embodiment, the interface unit can be attached or integrated to a piece of clothing at the shoulder of the user, with the audio signals from the speaker directed towards one of the user's ears. The wireless communication system can be applied to a number of different areas, including a communication device, such as a cell phone; a hearing aid; an entertainment system; and a computation system, such as a personal digital assistant or a computer.
