TL;DR: A programmable firmware store for a personal computer system includes a plurality of nonvolatile alterable electronic memories connected in a mutually paralleled circuit arrangement as discussed by the authors, which are connected to a controller that controls the memories to read firmware from and write firmware into the electronic memories, and to protect at least one of the memories.
Abstract: A programmable firmware store for a personal computer system includes a plurality of nonvolatile alterable electronic memories connected in a mutually paralleled circuit arrangement. The memories are connected to a controller that controls the memories to read firmware from and write firmware into the electronic memories, and to write-protect at least one of the memories. Any memory can be write-protected as initially selected by a user or technician of the system. The initial selection can be changed easily to write-protect another of the memories. The firmware in one memory includes code for checking the validity of firmware stored in another memory, and for selecting one or the other of the memories dependent upon a version code of the firmware. The controller also includes an update code for updating the firmware in a selected memory.

TL;DR: In this paper, a system for combining an electronic mail (email) address or addresses and/or facsimile telephone numbers into a fax message, so that when received by a server the fax document is processed and transmitted as an email attachment to the email addresses or fax message to the telephone numbers of the intended fax recipients.
Abstract: This invention relates to a system for combining an electronic mail (email) address or addresses and/or facsimile telephone numbers into a fax message, so that when received by a server the fax document is processed and transmitted as an email attachment to the email addresses or a fax message to the telephone numbers of the intended fax recipients. This allows the user to be able to send faxes and emails from a conventional fax machine or personal computer without having an Internet connection.

TL;DR: This article compares the data quality between two survey modes: self-administered web surveys conducted via personal computer and those conducted via mobile phones, and finds mobile web was associated with a lower completion rate, shorter length of open answers, and similar level of socially undesirable and non-substantive responses.
Abstract: The considerable growth in the number of smart mobile devices with a fast Internet connection provides new challenges for survey researchers. In this article, I compare the data quality between two survey modes: self-administered web surveys conducted via personal computer and those conducted via mobile phones. Data quality is compared based on five indicators: (a) completion rates, (b) response order effects, (c) social desirability, (d) non-substantive responses, and (e) length of open answers. I hypothesized that mobile web surveys would result in lower completion rates, stronger response order effects, and less elaborate answers to open-ended questions. No difference was expected in the level of reporting in sensitive items and in the rate of non-substantive responses. To test the assumptions, an experiment with two survey modes was conducted using a volunteer online access panel in Russia. As expected, mobile web was associated with a lower completion rate, shorter length of open answers, and similar level of socially undesirable and non-substantive responses. However, no stronger primacy effects in mobile web survey mode were found.

TL;DR: An improved hearing-related analysis programming system with a host computer for providing at least one hearing aid program and having at least a personal computer memory card international association (PCMCIA) defined port in combination with a PCMCIA card inserted in the port and arranged for interacting with the host computer as discussed by the authors.
Abstract: An improved hearing-related analysis programming system with a host computer for providing at least one hearing aid program and having at least one personal computer memory card international association (PCMCIA) defined port in combination with a PCMCIA Card inserted in the port and arranged for interacting with the host computer for controlling hearing-related analysis or programming of a hearing aid. The host computer provides power and ground to the PCMCIA Card and provides for downloading the hearing aid programming software to the PCMCIA Card upon initialization. A microprocessor on the PCMCIA Card executes hearing-related analysis or the programming software. A hearing aid interface for adjusting voltage levels and impedance levels is adapted for coupling signals to the hearing aid being programmed. Systems for performing hearing-related analysis include a portable audiometer system on a PCMCIA Card and operable with a portable host computer to analyze hearing of a patient, and a real-ear system on a PCMCIA Card and operable with a portable host computer to analyze output from a hearing aid in a patient's ear.

TL;DR: The new telemetry transmitter has, thus far, been used for in vivo load measurements in three patients with shoulder endoprostheses, and eight instrumented vertebral body replacements are ready for implantation and an instrumented tibial tray is being submitted to laboratory tests.
Abstract: Knowledge of the loads to which orthopedic implants are subjected is a fundamental prerequisite for their optimal biomechanical design, long-term success, and improved rehabilitation outcomes. In vivo load measurements are more accurate than those obtained using mathematical musculoskeletal models. An inductively powered integrated circuit inside the implant measures six load components as well as the temperature and supplied voltage. This low-power circuit includes a 9-channel multiplexer, a programmable memory, a pulse interval modulator, and a radio-frequency transmitter. Together with a few passive components, the integrated circuit is mounted on a ceramic substrate with thick-film hybrid technology. The sensor signals are multiplexed, modulated, and transmitted to an external device. The microcontroller of the external device regulates the alternating magnetic field produced by a power oscillator and synchronizes the pulse interval modulated data stream. A personal computer displays forces, moments, and temperatures in real time. The new telemetry transmitter has, thus far, been used for in vivo load measurements in three patients with shoulder endoprostheses. Eight instrumented vertebral body replacements are ready for implantation, and an instrumented tibial tray is being submitted to laboratory tests
