摘要:
A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.

Controls for stirrers, hot plates and stirring hot plates provide respective user interfaces having a single control knob that is used to provide a plurality of setpoints. The control permits a user to pause a stirring operation of stirrers and stirring hot plates, unload a vessel, load a new vessel, and restart the stirring without having to re-enter a speed setpoint. Also, current operational parameters may be stored as preset setpoints. The control further permits a user to program a calibration temperature that is similar to the temperatures expected to be encountered during operation.

A cortical stimulator system is provided. The system may include; a stimulation device having a switch configured to selectively control various electrodes; and a user interface device operatively connected to the stimulation device for controlling the electronic switch and stimulation device, the cortical stimulator system configured to provide a report of provided stimulation. A method of operating a cortical stimulator may be provided. The method may include: connecting a set of probes to the cortical stimulator, selecting parameters regarding a signal to be sent to the set of probes, sending a signal to the set of probes; observing the response of a subject having the set of probes contacting the subjects brain when the signal is sent to the probes, entering the observed response into the cortical stimulator, associating the response to a specific set of probes, and generating a report describing the response and associated probes.
摘要:
A cable for enhancing biopotential measurements, including a core, the core including a first conductive line, a first shield that surrounds the first conductive line, and a first insulator that surrounds the first shield. The cable further includes a control section located outside the core, which includes a second conductive line, a second shield that surrounds the conductive line, and a second insulator that surrounds the second shield.
