Abstract: Noise abatement within a signal stream containing unwanted signal referred to as noise is performed by acquiring a digitized noise signal and using a digital processor circuit to subdivide the acquired noise signal into different frequency band segments and thereby generate a plurality of segmented noise signals. Then individually for each segmented noise signal, the processor shifts in time the segmented noise signal by an amount dependent on a selected frequency of the segmented noise signal to produce a plurality of shifted segmented noise signals. The precise time shift applied to each noise segment considers the frequency content of the segment and the system processing time. Individually for each segmented noise signal, amplitude scaling is applied. The shifted and amplitude-scaled segmented noise signals are then combined to form a composite anti-noise signal which is output into the signal stream to abate the noise through destructive interference.

Abstract: A noise cancellation technique is presented with improved frequency resolution. The method includes: acquiring a digitized noise signal from an environment in which the audio signal stream is present; receiving a data sample from the digitized noise signal; appending one or more additional samples to the data sample to form a series of samples, where magnitude for each of the one or more additional samples is substantially zero; computing a frequency domain representation of the series of samples in the frequency domain; shifting the frequency domain representation of the series of samples in time using the digital processor circuit, thereby producing a shifted frequency domain representation of the series of samples; converting the shifted frequency domain representation of the series of samples to time domain to form a portion of an anti-noise signal; and outputting the anti-noise signal into the audio signal stream to abate the noise through destructive interference.

Abstract: The patient device, designed for use by patients of reduced cognitive or physical ability, integrates with the network-based portal, designed for use by family members or nursing staff to customize the user experience of the patient. Using the portal the family member pushes user interface customizations as well as content and applications to be run on the patient device. The family member can also control the patient device remotely via the portal. The patient device collects usage data on the set of customizable interface components, and on the pushed content and applications. These data are sent as feedback to the portal, allowing the portal to show the family member which user interface features, content and applications are being used and which are not. Aggregate data collected via the portal generate ranking metrics used to aid in user interface feature selection.

Abstract: The conference room automation apparatus employs a processor-based integrated movement sensor, lights, cameras, and display device, such as a projector, that senses and interprets human movement within the room to control the projector in response to that movement and that captures events occurring in the room. Preferably packed in a common integrated package, the apparatus employs a layered software/hardware architecture that may be readily extended as a platform to support additional third-party functionality.

Abstract: The system includes a computer-readable memory having a data structure configured to store information about a time-based event for a patient having reduced cognitive abilities, and optionally also electronic data reflecting the patient's cognitive ability. A networked computer system coupled to the computer-readable memory provides an information communicating interface to the patient. The computer system is programmed to monitor context information relevant to the patient and to dynamically adjust the presentation of the stored information based on the context, and optionally also based upon the patient's cognitive ability.

Abstract: The system includes a computer-readable memory having a data structure configured with electronic data indicative of the patient's cognitive ability and/or context information relevant to the patient. The computer system is programmed to dynamically present information based on the patient's cognitive ability and/or context, obtained by accessing the computer-readable memory. The system is thus able to dynamically customize the way the system interacts with the patient, dynamically rendering information and automatically launching specific applications and events based on set parameters to meet the assistive needs of the patient. The system also captures information about the patient's health and wellbeing which is dynamically communicated to the caregiver, which information is also in part based on cognitive ability of the patient and/or context.

Abstract: A wireless device participates in a mirroring session with an external device such as a display device. A radio signal monitoring circuit compares instantaneous wireless signal strength against a dynamically generated set of thresholds and initiates action to terminate the mirroring session when the mobile device physically moves from the initial location at which the mirroring session was established.
