Abstract: A method initiates and/or prepares a teleoperation by a robotic system for medical or surgical teleoperation. A hand-held master device is mechanically unconstrained and moved by an operator. A slave device includes a microsurgical instrument controlled by the master device. The robotic system includes a man-machine interface allowing the operator to communicate the intention to teleoperate to the robot. The method includes initiating teleoperation preparation; then performing alignment between master device and slave device, in which the slave device moves to align orientation of the surgical instrument to the master device. Teleoperation is entered after the alignment master and slave devices has been completed. First checks are conducted for entering the alignment, and enabling start of the alignment only if all first checks are passed. Before entering the teleoperation, second checks are conducted for enabling alignment, and enabling entry into teleoperation only if all second checks are passed.

Abstract: A method initiates and/or prepares and/or conducts teleoperation by a robotic system for medical or surgical teleoperation. The robotic system includes a master device, which is hand-held, mechanically unconstrained and moveable by an operator, and a slave device including a surgical instrument controlled by the master device. The master device is functionally symmetrical with respect to a predeterminable single, longitudinal axis of the master device. A local reference frame of the master device and the related longitudinal axis is detected, with respect to a main reference frame of the master device workspace; then, functionally equivalent local reference frames are detected. A corresponding target reference frame is mapped in a workspace of the slave device. An operating reference frame is detected according to criteria for optimization of the trajectory of the slave device. A robotic system for medical or surgical teleoperation is control led by the control method.

Abstract: Described herein relates to an apparatus and method for developmental and/or rehabilitative sensory substitution to augment at least one low-functioning and/or non-functioning senses in at least one user. The apparatus may include an input module that may allow the user to perform various tasks designed to enhance development of or sensory recognition by the user. The apparatus may be capable of multiple different proportional controls and of being used across ages, sizes, and developmental stages. For example, the apparatus may include at least one joystick, button, lever, and accelerometer, such that a sensory feedback response (e.g., haptic/tactile, visual, and/or auditory) may be provided to the user across a plurality of exercises. Additionally, the apparatus may provide a new standard of care for individuals with special needs and/or those recovering from a traumatic physical and/or mental injury, regardless of ability level and age.

Abstract: A modular ride-on is provided that is adjustable based on the needs of the operator. The modular ride-on offers children and young adults with disabilities a higher degree of freedom and comfort over traditional mobility devices—such as wheelchairs. The modular ride-on includes a chassis configured to removably couple a plurality of adjustable modules. The independently adjustable modules include a front-end module, first and second drive modules, a seating module, a harness module, an armrest module, a footrest module, a leg support, module, a body module, and a control module.

Abstract: Trusted nodes in a network perform secure out-of-band symmetric encryption key delivery to user devices. A first trusted node receives a request from a first user device to deliver symmetric encryption keys to the first user device and a second user device, as a pair of user devices. The first trusted node delivers a second symmetric encryption key to the second user device, via trusted nodes. The first trusted node receives confirmation of delivery of the second symmetric encryption key. Responsive to the confirmation of delivery, the first trusted node delivers the first symmetric encryption key to the first user device.

Abstract: A disposable cover for a contact tonometer probe tip. The cover includes a tubular body and a cover tip. The tubular body is defined by a wall having an outer surface and an inner surface, and defines distal, proximal, and intermediate sections. The distal section terminates at a distal end, and the proximal section terminates at an open, proximal end. The proximal section forms a radial channel configured to mate with a corresponding feature of a probe tip and is characterized by an increased inner diameter. The outer surface along the intermediate section defines a conical shape that decreases in diameter from the proximal section to the distal section. Finally, the cover tip is formed at the distal end of the tubular body such that the cover is closed at the distal end.

Abstract: The invention provides a hypoallergenic disposable cover for the probe tip of a contact tonometer comprising a thin film having an ultimate elongation in the range of 500 to 1000%, a tensile strength in the range of 1000 to 5500 psi and a modulus of elasticity at 100% strain in the range of 50 to 2000 psi, whereby when installed onto the probe tip, the cover creates a barrier against microorganisms from the eye of a patient to said probe tip during a tonometric examination while allowing measurement of intraocular pressure through the disposable tip cover.

Abstract: Methods for determining the extent and nature of porosity in dielectric materials, particularly in thin dielectric films, using electrochemical impedance spectroscopy are disclosed. Such methods are useful in the manufacture of integrated circuits having porous dielectric layers.
