A packaging assembly comprises a case configured to at least partially contain a plurality of injection devices for delivering a medicament; and a sensor arrangement comprising at least one device sensor; wherein the at least one device sensor is configured to detect one or more injection devices contained in the case, and to output a signal according to a result of the detection.

An image processing device is an image processing device configured to cause a display to display three-dimensional data as a three-dimensional image, the three-dimensional data representing a biological tissue. The image processing device includes: a control unit configured to adjust a color tone of each pixel of the three-dimensional image according to a dimension of the biological tissue in a linear direction from a viewpoint when the three-dimensional image is displayed on the display.

An image processing device is an image processing device configured to cause a display to display three-dimensional data as a three-dimensional image, the three-dimensional data representing a biological tissue. The image processing device includes: a control unit configured to detect a series of positions of a catheter inserted into the biological tissue from data obtained in time series by a sensor observing the surrounding of a lumen of the biological tissue while moving in the lumen, and to switch a display mode between a first mode for displaying a first figure representing the series of positions in the three-dimensional image, and a second mode for displaying a second figure representing one position among the series of positions in the three-dimensional image.

Embodiments of the invention are directed towards systems, methods and computer program products for providing improved eye tests. Such tests improve upon current eye tests, such as visual field tests, by incorporating virtual reality, software mediated guidance to the patient or practitioner such that more accurate results of the eye tests are obtained. Furthermore, through the use of one or more trained machine learning or predictive analytic systems, multiple signals obtained from sensors of a testing apparatus are evaluated to ensure that the eye test results are less error-prone and provide a more consistent evaluation of a user's vision status. As it will be appreciated, such error reduction and user guidance systems represent technological improvements in eye tests and utilize non-routine and non-conventional approaches to the improvement and reliability of eye tests.

An electrocardiography device is described that can include a main body, an adjustable cap, and a power switch. The main body can include an electrode of a plurality of electrodes configured to acquire electrical signal from a patient. The adjustable cap can include two electrodes of the plurality of electrodes. The adjustable cap can be rotatable around an axis on the main body to orient the plurality of electrodes on different locations on a body of the patient. The power switch can activate the plurality of electrodes to acquire the electrical signal from the patient. Related apparatuses, systems, methods, techniques and articles are also described.

An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.

Systems and Methods are disclosed for real-time decryption of a health registry-issued certificate for signaling a user vaccination and/or test status on a user device comprising the steps of: coupling a first user mobile device to a health registry for real-time decryption of a health registry-issued health certificate over a network; outputting on the first user mobile device at least one of an audible output, visual output, vibrational output, and/or textual output based on a pre-defined signaling protocol to signal a user vaccination status based on a token derived from the real-time decrypted health certificate; and decoding a device identifier/tag or token from the first user mobile device by a second user mobile device, fixed access device, or hand-held scanner, signaling to a second user a first user vaccination status based on a pre-defined signaling protocol and the tag/token.

A portable ultrasonic diagnostic apparatus and a method of controlling the same are provided, including a flexible display and a controller which changes a layout of an image displayed on the flexible display. An image necessary for diagnosing an object is appropriately disposed on a flexible display according to a situation, and thus, the user can intuitively determine an ultrasonic image.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.
