Abstract: A method for detecting an analyte in a plant is provided. The method includes injecting an analyte-capture agent into a leaf of a plant, and in the leaf, optically detecting complexes formed by capturing an analyte with the injected analyte-capture agent. The analyte-capture agent can include an analyte-interacting component connected to a microcarrier. In particular versions, the analyte-capture agent can be an analyte specific antibody or aptamer, and the microcarrier can be a polydiacetylene liposome. Binding of the analyte can cause a change in color of the liposome, thus indicating the presence of the analyte.

Abstract: An endoscopic stapler is disclosed. The stapler includes a staple member and an anvil member. The staple member may include a staple housing and the staple holder may include one or more staples. The anvil member may be spaced apart from the staple member and may configured to relatively move towards one another. A controller may be fluidly coupled to the staple member through a plurality of conduits. The controller may be configured to (a) direct a pressurized fluid to the staple member through a first conduit of the plurality of conduits to relatively move the staple member and the anvil member towards one another, and (b) direct the pressurize fluid through a second conduit of the plurality of conduits to eject one or more staples from the staple holder.

Abstract: A power module includes a first substrate having a metallized side, a second substrate spaced apart from the first substrate and having a metallized side facing the metallized side of the first substrate, and a semiconductor die interposed between the first and second substrates. The semiconductor die has a first side connected to the metallized side of the first substrate and an opposing second side connected to the metallized side of the second substrate. The power module further includes a sensor connected to the metallized side of the first substrate and galvanically isolated from the metallized side of the second substrate. The sensor is aligned with a first metal region of the metallized side of the second substrate so that the sensor can measure a magnetic field generated by the first metal region.

Abstract: An example of a device comprises a signal generator to generate a signal causing a magnetic self test field for a magneto-resistive sensing element. A signal input is configures to receive a first sensor signal at a first time instant before the magnetic self test field is applied and a second sensor signal at a second time instant after the magnetic self test field is applied. An evaluation circuit is configured to determine information indicating a safe operation based on an evaluation of the first sensor signal and the second sensor signal.

Abstract: A cooling system for molded modules includes a plurality of individual modules each including a semiconductor die encapsulated by a mold compound, a plurality of leads electrically connected to the semiconductor die and at least partly uncovered by the mold compound, and a cooling plate at least partly uncovered by the mold compound. A molded body surrounds a periphery of each individual module to form a multi-die module. The leads of each individual module and the cooling plates are at least partly uncovered by the molded body. A lid with a port is attached to a periphery of the molded body at a first side of the multi-die module. The lid seals the multi-die module at the first side to form a cavity between the lid and the molded body for permitting fluid exiting or entering the port to contact the cooling plates of each individual module.

Abstract: Systems, apparatus, and methods for non-invasively detecting a white blood cell (WBC) event from in vivo capillary data may include obtaining a plurality of images, followed by specifying two-dimensional (2D) coordinates corresponding to internal contour and external contour of a capillary visible in the images. The two sets of 2D coordinates may be resampled to generate two sets of resampled coordinates, between which intermediate curves, including a middle curve, are generated. Curvilinear distances may be defined based on the middle curve. Intensity values, each of which corresponds to one of the images, one of the intermediate curves, and one of the curvilinear distances, may be extracted and transformed to the Radon domain. A plurality of maxima locations in the Radon domain corresponding to a flow trajectory inside the capillary may be identified. Detection of a visual gap in the flow trajectory inside the capillary indicates a WBC event.
