Abstract: Methods, devices and systems are disclosed for inter-app communications between software applications on a mobile communications device. In one aspect, a computer-readable medium on a mobile computing device comprising an inter-application communication data structure to facilitate transitioning and distributing data between software applications in a shared app group for an operating system of the mobile computing device includes a scheme field of the data structure providing a scheme id associated with a target software app to transition to from a source software app, wherein the scheme id is listed on a scheme list stored with the source software app; and a payload field of the data structure providing data and/or an identification where to access data in a shared file system accessible to the software applications in the shared app group, wherein the payload field is encrypted.

Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

Abstract: Described herein is a composition for producing a thiol-ene covalent adaptable network (CAN) polymer. The composition includes a first monomer including at least one thiol group; and a second monomer including at least one anhydride functional group and at least one alkene functional group. Also described herein are a polymer produced from the composition, a method of producing the polymer using the composition, a method of fabricating a polymer article using the composition, as well as a method of degrading the polymer.

Abstract: An optical fiber shutter adapter including a housing having a bay and a bay opening for receiving a second connector. The optical fiber shutter adapter further includes a door disposed near the bay opening and having a blocking portion for blocking laser radiation from being emitted from the bay opening when the door is in a closed position. The door is connected to the housing for movement from the closed position to an open position for allowing the second connector to be received into the bay for connection to the shutter adapter. The blocking portion of the door moves into the adapter housing when the door is moved from the closed position towards the open position.
