Abstract
Electronic test devices and methods include data transfer capabilities. In one implementation, an assay device includes wireless communication capabilities to send assay result decisions and/or values to a separate processing and display device such as a smartphone. In another implementation, light sources are modulated both for performing an assay and encoding and transmitting a result of an assay.
Claims11
A test device comprising:
- assay electronics configured for conducting an assay to generate an assay result indicating the presence, absence, amount, degree, or severity of a chemical, physical, biological, medical, or environmental condition from a sample of material provided to the test device;
- a wireless transmitter coupled to the assay electronics;
- wherein the assay electronics is configured to detect a test initiation event;
- wherein the assay electronics is configured to send a start signal to the wireless transmitter which wirelessly transmits the start signal to an external processing and display device separate from the test device in response to detecting the test initiation event;
- wherein the assay electronics is configured to generate assay measurement data and process that assay measurement data into a single assay result;
- and
- wherein the assay electronics is configured to send the single assay result to the wireless transmitter which wirelessly transmits the single assay result to the external processing and display device separate from the test device.
4 more elements
A method of testing, the method comprising:
- establishing a wireless communication channel between a test device in a first housing and a display device in a physically separate second housing;
- receiving a sample for testing at the test device;
- detecting, at the test device, a test timer initiation event;
- transmitting a test initiation message from the test device to the display device;
- in response to receiving the test initiation message, initiating and displaying a timer on the display device configured to identify an end time for the testing;
- upon the end time for the testing, obtaining a result of the testing at the display device from the test device;
- and
- displaying the received result on the display device.
5 more elements
A testing system comprising:
- a test device including:
- a processor;
- means for receiving a test stick;
- means for conducting an assay configured to:
- detect a test timer initiation event;
- and
- generate a result indicating the presence or absence of a substance contained in a sample provided via a test stick received via the means for receiving a test stick;
- a first wireless transceiver configured to:
- transmit a test initiation message using the test timer initiation event via a communication channel;
- and
- transmit the test result via the communication channel;
- an external display device separate from the test device including:
- a second wireless transceiver configured to:
- establish the communication channel with the test device;
- receive the test initiation message from the test device via the communication channel;
- and
- receive the test result from the test device;
- and
- a timer, wherein the timer is started in response to receiving the test initiation message;
- a display configured to:
- in response to establishing the communication channel, display a connection status message;
- and
- display a value of the timer.
20 more elements
A handheld, single use, disposable chemical assay device comprising:
- a housing;
- assay electronics contained within the housing configured to detect a test initiation event and to generate a result for an assay performed during a period of time after the test initiation event;
- a display coupled to the housing and the assay electronics configured to display the result of the assay received from the assay electronics;
- a wireless transmitter contained within the housing;
- wherein the assay electronics and the wireless transmitter are configured to transmit both a start signal in response to the detection of the test initiation event and the result of the assay performed after the test initiation event to an external processing and display device.
