Publication number: 20140129015Abstract: Various techniques relating to the buffering of a live audio broadcast on an electronic device and the subsequently playback the buffered data are provided. In one embodiment, the playback speed of the buffered data may be increased relative to the actual speed at which the data was originally broadcasted. If the buffered playback (using the increased playback speed) synchronizes or catches up to the live broadcast, the electronic device may disable buffering and output the live stream instead. This decreases processing demands by lowering processing cycles required for buffering (encoding, etc.) and playback of the buffered data (decoding, etc.), thereby reducing power consumption.Type: ApplicationFiled: January 13, 2014Publication date: May 8, 2014Applicant: Apple Inc.Inventors: Aram Lindahl, Richard M.

Patent number: 8473084Abstract: Techniques are presented for dynamically controlling an audio crossfade from a first audio track to a second audio track. The first audio track may be decoded and buffered to a first buffer. A user may select a second audio track at some point during playback of the first audio track. The second audio track may be decoded, and a processor may access the decoded second audio track and the buffered first audio track and mix the two audio tracks. The mixed audio track may be inserted in the same first buffer near or at the read pointer of the first buffer, such that latency between the user selection and the crossfade into the selected audio track may be minimized. The insertion of the mixed audio track may depend on various factors, including the type of audio file and/or the decoder type used to decode the second audio track.Type: GrantFiled: September 1, 2010Date of Patent: June 25, 2013Assignee: Apple Inc.Inventors: Aram Lindahl, Alexander Kanaris, Joseph M.

Patent number: 5549654Abstract: An automatic implantable device system including an implantable device which communicates with an external programming unit via uplink and downlink telemetry. The implanted device is capable of transmitting event markers to the external device, the event markers reflecting the occurrence of identified physiologic and device-initiated events. The external device includes circuitry for generating an interactive diagram illustrating the interrelation between marker events, and a display screen for presenting a graphical image of the marker diagram to the user. In addition, the external device defines a plurality of "hot spots" in the area of the diagram, such that when a user selects a particular area of the diagram on the display, using, for example, a mouse or other cursor control device, a context-sensitive explanatory message is displayed to the user. In the disclosed embodiment, expert system software is executed by a computer subsystem of the external device.Type: GrantFiled: April 15, 1994Date of Patent: August 27, 1996Assignee: Medtronic, Inc.Inventor: Richard M.

Patent number: 5447525Abstract: A cardiac pacemaker improves battery longevity by automatically providing a safe threshold and an associated pulse width leading to minimum current drain. The pacemaker stores a matrix of current drain characteristics for all of the possible pulse width-voltage pairs, and a revisable strength-duration curve for a patient. Either periodically or as a result of a loss-of-capture episode--whichever occurs first--the pacemaker calculates for each possible pulse width, a new threshold value based upon a measured rheobase and a derived chronaxie. Each threshold is multiplied by a predetermined safety margin. The pacemaker chooses as the pacing stimulation signal, the voltage-pulse width pair having the lowest associated current drain, and satisfying the desired safety margin.Type: GrantFiled: September 15, 1993Date of Patent: September 5, 1995Assignee: Medtronic, Inc.Inventors: Richard M. Powell, Steven L. Jensen

Patent number: 5372607Abstract: A method and apparatus for optimizing the performance of a rate-responsive cardiac pacemaker. A pacemaker is provided which is capable of obtaining and storing information about a patient's cardiac function and about a pacemaker's operation during a brief exercise interval. The data collected includes information about the number of cardiac events during each two-second interval of the exercise, as well as the percentage of paced events during each two-second interval. Data reflecting the output of the pacemaker's activity sensor output is also collected for each two second interval of the test. In addition, AV interval data for each cardiac cycle during the test is collected, this data being distinguished according to whether it reflects atrial-pace-to-ventricular-sense or atrial-sense-to-ventricular-sense AV intervals. The disclosed pacemaker is operable in conjunction with an external programming/processing unit, which receives the stored data after the exercise test is concluded.Type: GrantFiled: June 23, 1993Date of Patent: December 13, 1994Assignee: Medtronic, Inc.Inventors: Karen A. Stone, Richard M. Powell, Michael R. Tollinger, Gary Berg

Patent number: 4250884Abstract: A method and apparatus is disclosed for programming a threshold mode of operation into a pacing generator whereby the minimum level of energy of the stimulating pulse as generated by the pacing generator is determined. First, the original level of energy of the stimulating pulses is determined when this mode is commenced. The original energy level and in particular the pulse width is decremented by a predetermined incremental amount, and an encoded signal indicative of the new reduced pulse width is transmitted to the pacing generator, whereby the pacing generator applies the pulses of the reduced pulse width to the patient's heart. Further, there is included means for counting the number of pulses of reduced pulse width and after the application of a given number of pulses by the pacing generator to the patient's heart, the programming apparatus programs a new energy level decremented from the previously programmed value to be then transmitted to the pacing generator.Type: GrantFiled: November 6, 1978Date of Patent: February 17, 1981Assignee: Medtronic, Inc.Inventors: Jerome T. Hartlaub, Bobby L. Smith, Richard M. Powell

Patent number: 4236524Abstract: A programmer is disclosed for transmitting encoded signals to a pacing generator to effect the programming of a mode and/or parameter of the pacering generator's operation. The pacing generator applies stimulating pulses to the patient's heart in accordance with the programmed parameters and/or mode and includes a memory for storing the encoded signals and means therein for detecting the successful storage of the parameters in the memory to provide an indication thereof, whereby a generating circuit of the pacing generator generates a test or PIP pulse of given characteristics and within a defined interval after the pacing pulse.Type: GrantFiled: November 6, 1978Date of Patent: December 2, 1980Assignee: Medtronic, Inc.Inventors: Richard M.
