A wearable electronic device is disclosed, including: a housing having a front plate disposed facing in a first direction, a rear plate disposed facing in a second direction opposite to the first direction, at least a part of the rear plate substantially transparent, and a side member defining a space between the front plate and the rear plate, a substrate disposed within the space, a biometric sensor module disposed between the substrate and the rear plate including at least one light source configured to emit light to an exterior of the wearable electronic device and at least one light detector configured to receive reflected light corresponding to the emitted light reflected from the exterior, and at least one magnetic substance disposed between the light source and the light detector to limit an amount of light reaching the biometric sensor module other than the reflected emitted light.

A multi-line electrical assembly that includes a multi-line cable (14), including a multiplicity of insulated conductive wires (59); and a multi-line electrical plug (16), physically connected to the cable. The plug has a housing (56) and a plurality of spaced-apart printed circuit hoards (PCBs, 48), housed in the housing and having a first end (47) that is connected to the cable and having a second end (46), separated from the first end. Further, the PCBs bear a plurality of conductive traces (50), at least some of the traces being electrically connected to the wires proximal to the first end. The traces terminate proximal to the second end.

The wheal and flare analyzing system analyzes the mast cell reaction to an allergen being administered in a scratch or prick skin test. The system comprises a sensor array and a processing unit. The sensor array includes a plurality of emitters surrounding a receiver at the allergen test site. Energy of various wavelengths is emitted into the allergen test site. An energy receiver measures reflected various wavelengths from the plurality of emitters. A microprocessor is in digital communication with the plurality of emitters and the energy receiver. The reflected wavelengths have an energy return indicative of the intensity of the allergic reaction in the mast cells. The intensity of the allergic reaction is analyzable from the reflected wavelengths and other data over time. A plurality of temperature sensors measuring local dermal temperatures surrounding the sensor array, the local dermal temperature being indicative of the intensity of the allergic reaction.

Systems and methods for delivering a drug or other therapy over an extended period of time (e.g., several hours, days, weeks, months, years, and so forth) are disclosed herein, as are systems and methods for monitoring various parameters associated with the treatment of a patient. Systems and methods are also disclosed herein that generally involve CED devices with various features for reducing or preventing backflow.

In one example, a display unit comprises a display panel that is configured to display digital images. The display unit further comprises an at least partially transparent protective layer that is arranged above the display panel. The display unit further comprises a controller that is communicatively attached onto an upper surface of the display panel. A biometric sensor pattern is integrated in the controller, and the controller is configured to control the biometric sensor pattern.

A method for integrating a thin film microbattery with electronic circuitry includes forming a release layer over a handler, forming a thin film microbattery over the release layer of the handler, removing the thin film microbattery from the handler, depositing the thin film microbattery on an interposer, forming electronic circuitry on the interposer, and sealing the thin film microbattery and the electronic circuitry to create individual microbattery modules.

The disclosed systems and methods provide a printed electronics breath indicator that may be directly printed or molded onto a manufactured breathing device, or separately attached to an existing breathing device. The printed electronics breath indicator may include an electroluminescent indicator, a sensor, and a processor. The processor may be configured to receive sensor data from the sensor, the sensor data including detected carbon dioxide (CO2) or oxygen (O2) levels. The processor may be further configured to determine a current breathing state of the patient based on the received sensor data. The processor may be further configured to cause the electroluminescent indicator to generate a visual representation according to the determined current breathing state of the patient. The visual representation may comprise a variable visual representation that displays one or more visual parameters that are proportional to the detected CO2 or O2 levels.
