A system and method for patient positioning during radiotherapy. The system can include a patient support structure configured to receive a patient during a radiotherapy process using a radiotherapy source to deliver a therapy to the patient when positioned on the patient support structure, a patient positioning system configured to adjust a position of the patient support structure relative to the radiotherapy source, a flexible actuator configured to secure the patient to the patient support and adjust a position of the patient relative to the patient support, and an imaging system configured to acquire imaging data of the patient, the patient support, and the flexible actuator during the radiotherapy process.

A method for detecting a user's intent in an adaptive lower limb device includes providing the adaptive lower limb device. The lower limb device includes a device control unit. The device control unit includes activity controllers and at least one accelerometer. The acceleration features are measured via the at least one accelerometer. The measured acceleration features are determined whether they correspond to a tapping movement initiated by a user with an intent to switch from a first one of the plurality of activity controllers to a second one of the plurality of activity controllers. If the measured accelerating features correspond to the tapping movement, the control unit of the adaptive lower limb device is switched from the first one of the activity controllers to the second one of the activity controllers.

A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is configured to move the jaw members and is configured to operably couple to a torque sensor that measures the torque of the input during rotation thereof. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the movement of the jaw members. A housing having a lever operably coupled thereto, houses components therein configured to operably connect to the input such that movement of the lever correlates to movement of the jaw members. The components are configured to regulate the resistance of the lever in response to the feedback from the torque sensor.

The present disclosure relates to the reduction of pressure ulcers and falls with respect to patients with physical or cognitive impairments who are in bed. A control system assures that the bed and ancillary apparatus are physically set and that patient behaviors are responded to by care providers. Motion is monitored with a non-mutually exclusive portfolio of sensors, and this information is used by one or more reasoning engines. An integrated clinical workflow is informed by the patterns of movement and then the physical environment, patient interaction, and care provider workflow are controlled to reduce the incidence of falls and pressure ulcers in bed ridden patients.

A load cell apparatus for use with a bed includes a housing having a top portion and a bottom portion, and a load cell device held by the bottom portion of the housing. The load cell device is structured to generate a signal having a magnitude that is proportional to a first force being applied to the load cell device. The load cell apparatus also includes a button member held by the housing in a manner wherein the button member is structured to engage the load cell device and apply the first force to the load cell device in response to a second force being applied to the top portion of the housing. Also, various systems for monitoring parameters such as weight, sleep quality, fall risk, and/or pressure sore risk that may incorporate such a load cell apparatus.

A system includes a sensor configured to generate data associated with movements of a resident for a period of time, a memory storing machine-readable instructions, and a control system arranged to provide control signals to one or more electronic devices. The control system also includes one or more processors configured to execute the machine-readable instructions to analyze the generated data associated with the movement of the resident, determine, based at least in part on the analysis, a likelihood for a fall event to occur for the resident within a predetermined amount of time, and responsive to the determination of the likelihood for the fall event satisfying a threshold, cause an operation of the one or more electronic devices to be modified.

A person support apparatus, such as a bed, stretcher, cot, recliner, or the like, includes an exit detection system having a plurality of force sensors that support the weight of an occupant positioned on a support surface and obstruction detection system having one or more obstruction sensors. The force sensors are part of an exit detection system that issues an alarm when the occupant exits, or is about to exit, the person support apparatus. The bed exit system can react to detection of an obstacle. The distribution of weight applied to the force sensors is used to determine if the occupant is about to exit the person support apparatus. Compensation is made to the exit detection system for changes in the weight distribution that are not caused by movement of the occupant. Such changes may be due to not only movement of the person support apparatus or components thereof, but obstacles encountered by the person support apparatus or components thereof.

The disclosure provides tissue force sensor systems and methods for tissues, e.g., laryngeal tissue. The systems include a top housing including on an upper side an attachment mechanism for connecting the top housing to a medical device, e.g., a laryngoscope, and on a lower side a first cavity for receiving a top portion of a force measurement device such as a load cell; a bottom housing including on a lower side an attachment mechanism for connecting the bottom housing to a handle, holding system, or suspension system for holding or supporting the medical device, and on an upper side a second cavity for receiving a bottom portion of the force measurement device; and an attachment device for connecting the top housing to the bottom housing.

The present disclosure provides systems, methods and apparatuses for inducing a desired biological response in an organism through the use of one or more repetitive signals from one or a series of LED lights designed to emit the signal with multiple pulsed components. Each component of the signal contains a one or more light color spectrum or wavelength that is within 50 nm of the peak absorption of a photon receptor of the organism corresponding to the desired biological response. Each component has a repetitive ON duration with an OFF duration and an intensity where the relationship between the ON duration and OFF duration of the first component and the second component induces the desired response in the organism through the stimulation or excitation of a molecule associated with a photoreceptor and the reset of the molecule.

The invention comprises a device and method to estimate the elasticity of soft elastic solids from surface wave measurements. The method is non-destructive, reliable and repeatable. The final device is low-cost and portable. It is based in audio-frequency shear wave propagation in elastic soft solids. Within this frequency range, shear wavelength is centimeter sized. Thus, the experimental data is usually collected in the near-field of the source. Therefore, an inversion algorithm taking into account near-field effects was developed for use with the device. Example applications are shown in beef samples, tissue mimicking materials and in vivo skeletal muscle of healthy volunteers.
