  • Patent number: 10702147
    Abstract: A system for conducting an examination of the eyes of a subject includes an examination instrument which emits light at infrared wavelengths, and a shield. The shield provides shielding of the subject's eyes from visible wavelengths. At least a portion of the shield is transparent to the infrared wavelengths emitted by the examination instrument. A related method of conducting an eye examination on a subject includes the step of providing a shield which is transparent to infrared wavelengths but nontransparent to visible wavelengths. The method also includes the step of carrying out the examination with an instrument which is located on the examiner facing side of the shield and which emits the infrared wavelengths to which the shield is transparent. One variant of the method determines parameters relating to the subject's eyes and/or vision using only information considered to be valid, validity being based on the subject's pupil diameter.

  • Patent number: 10616740
    Abstract: A method for connecting wireless devices using Bluetooth® low energy can be used to connect wireless computing devices with a medical device in an ambulatory care setting. The wireless computing devices can receive measured vital sign data and transmit the vital sign data to a patient's electronic medical record. The wireless computing devices can be configured to include a user-friendly name and the transmitter power in one or more advertising broadcasts. The medical device can receive advertising broadcasts from one or more wireless computing devices and sort the devices by proximity, last use, number of times used, or alphabetically. After the devices exchange information over Bluetooth® low energy, the devices can connect in Bluetooth® Classic. Systems for implementing the method are also disclosed.

  • Patent number: 10614914
    Abstract: A patient care environment includes a monitoring device and a vital sign device, where the vital sign device communicates patient vital sign data to the monitoring device. A site key, entity keys, and key combining algorithms are used to secure communications in the patient care environment. Neither the site key nor the entity keys are communicated between the monitoring device and the vital sign device. The monitoring device may use the site key and entity keys to decrypt encrypted messages that have been previously stored in the vital sign device and transmitted back to any monitoring device containing the correct set of site and entity keys. The site key and entity key may also be used during the discovery and/or connection operations between the monitoring device and the vital sign device to associate a wirelessly connected vital sign device with a patient record.
