摘要:
Apparatus and method support the configuration and testing of therapy parameters for a medical device system in the treatment of nervous system disorders. With the embodiment, the medical device system operates in a manual treatment therapy mode, in which the medical device system evaluates a set of information that is indicative of a system configuration. The medical device system determines if the set of information is acceptable. During the manual treatment therapy mode, the medical device system applies therapeutic treatment to a patient in accordance with the set of information. If the patient cannot tolerate the therapeutic treatment, the user indicates so through a user interface. The medical device system may associate the patient's intolerance to therapeutic treatments that equal or exceed the patient's level of tolerance. Moreover, the medical device system may use this information to prevent a delivery of therapeutic treatment that exceeds the patient's level of tolerance during a run mode.

Apparatus and method support the synchronization and calibration of a plurality of clocks in a medical device system that may provide treatment to a patient with a nervous system disorder. The plurality of clocks, which may be located at different components of the medical device system, includes a first clock and a second clock. The second clock may be synchronized to a first clock by disabling a run mode operation and setting the second clock to a selected time. When a reference time of the first clock approximately equals the selected time, the second clock enables the run mode operation. Additionally, a drift time that is indicative of a time difference between the first clock and the second clock is determined. If the drift time is greater than a predetermined amount, an indication to resynchronize the first and second clocks is provided.

Apparatus and method support a neurological event screening for a medical device. The medical device assists a user in determining a configuration of the medical device for delivering an effective treatment for a nervous system disorder. The medical device detects a neurological event, such as a seizure, and reports a neurological event focus location and a neurological event spread to the user. The user may use the information to provide a configuration of a therapeutic delivery unit and associated therapy parameters. Therapeutic treatment is delivered to the patient, and the medical device is provided an indication of the patient's acceptance to the treatment. The user may modify the configuration and therapy parameters in order to achieve efficacy and acceptance. Depending upon the patient's acceptance, therapy is applied in either an open loop mode or a closed loop mode. The medical device determines whether the treatment is successful in accordance with a criterion.

A ZnS:Tm,Ag cathodoluminescent phosphor composition is described. The phosphor emits in the infrared region at approximately 800 nm. The method of making this phosphor is also described. The ingredients are mixed, formed into a cake, dried, comminuted, heated at 800.degree. C. followed by a 1180.degree. C. firing and then cooled to room temperature. All the heating and cooling is done in a hydrogen sulfide atmosphere.

The instant invention relates to a method of preparing an electrical contact from sub-micron size silver and less than two micron size cadmium oxide particles with the contact having finally dispersed particles of cadmium oxide within grains of silver. In the instant invention the particles of silver and cadmium oxide are intimately blended together and subjected to a reducing atmosphere at a temperature of from 321.degree. C. to 550.degree. C. to reduce the cadmium oxide and form an alloy powder of cadmium and silver. The alloy formed is held at an elevated temperature following reducing and then oxidized at a temperature of from 321.degree. C. to 550.degree. C. to precipitate a dispersion of cadmium oxide within grains of silver and form a silver-cadmium oxide alloy powder. In an alternative embodiment an alloy powder of cadmium and silver already prepared from sub-micron size particles of silver and less than two micron size particles of cadmium oxide is heated to a temperature of from 321.degree. C. to 550.degree. C. in an inert atmosphere. The inert atmosphere is then changed to an oxidizing atmosphere at that temperature to precipitate the dispersion of cadmium oxide within the grains of silver. The material as prepared by both embodiments is then formed into an electrical contact.

A new and improved method of treating a manganese activated zinc silicate phosphor is described. The method comprises heating a manganese activated zinc silicate phosphor powder having cations consisting essentially of zinc, silicon, manganese, and tungsten and having a 350 nm reflectance less than 80% and a 275 nm reflectance greater than 13.5% to a temperature of about 1225.degree. C. in air. The phosphor powder is then cooled to room temperature and wet milled in an acid solution. The phosphor powder is then separated from the acid solution washed in water and dried to form a dry phosphor powder having a 350 nm reflectance equal to or greater than 80% and a 275 nm reflectance equal to or less than 13.5%.
