The disclosure generally relates to providing a network of security volunteers who can opt-in to provide security services and / or a physical presence to deter, distract, delay, or prevent a potentially threatening situation. Security volunteers can receive alerts from a central monitoring center regarding nearby distress signals sent from a victim's device, and can then proceed to the location of the victim. Security volunteers can view their location and the location of the victim on a map on their mobile devices, as well as communicate with a victim's device, the central monitoring center, and other security volunteers who are responding to the scene.

A haptic feedback device including a fluid viscosity-controlled brake that outputs high forces to the device user at low cost while maintaining inherent safety. An interface device includes a manipulandum physically contacted by the user. A sensor senses a position of the manipulandum and outputs a sensor signal. The interface device also includes a brake including a field-controlled fluid having a viscosity that can be controlled by controlling an electric current in a coil, where a resistive force or drag on the manipulandum is controlled by controlling the fluid's viscosity. The fluid can be an electrorheological fluid controlled by an electric field or a magnetorheological fluid controlled by a magnetic field. In one preferred embodiment, the resistive force is controlled by adjusting a degree of contact of the brake with the manipulandum based on the fluid's viscosity. Disclosed embodiments include fishing devices, bicycle simulators, and control knobs.

In order to maintain high security of a job that requires a high security level even after a print interrupt factor has been removed, and to achieve both the effect of maintaining high security of a job that requires a high security level even after the print process is interrupted, and the effect of improving the productivity of jobs other than a job of this type, when a print apparatus which can process a plurality of print jobs including a print job of a first type and that of a second type restarts a print operation of a print job, which is interrupted in the print apparatus, and when the print job is a print of the first type, the print apparatus is controlled to execute an authentication process, and then allowed to restart the print operation of the print job. When the print apparatus restarts a print operation of a print job, which is interrupted in the print apparatus, and when the print job is a print of the second type, the print apparatus is allowed to restart the print operation of the print job without executing the authentication process.

The disclosure generally relates to methods and systems anticipating a potentially threatening or dangerous incident, and providing varying levels of response to a user. In an exemplary embodiment, the present invention provides varying levels of assistance to a user prior to, during, and after a threatening incident occurs. By providing assistance prior to a threatening incident occurring, the system may be able to thwart potential attacks, bodily harm, robberies, break-ins, and other criminal or dangerous activity. The assistance can be, for example, in the form of deterrents, alerting first responders to go to the scene, sending security personnel to the scene, remotely monitoring the scene, remotely interacting with the scene, providing information and advice to the user.

Improved systems, devices, and methods for delivering cryogenic cooling fluid to cryosurgical probes such as cryosurgical endovascular balloon catheters take advantage of the transients during the initiation and termination of cryogenic fluid flow to moderate the treatment temperatures of tissues engaged by the probe. A flow limiting element along a cryogenic fluid path intermittently interrupts the flow of cooling fluid, often cycling both the fluid flow and treatment temperature. This can maintain the tissue treatment temperature within a predetermined range which is above the treatment temperature provided by a steady flow of cryogenic fluid. In another aspect, room temperature single-use cooling fluid cartridges are filled with a sufficient quantity of cryosurgical fluid to effect a desired endovascular cryosurgical treatment.

A method and apparatus for controlling blood withdrawal and infusion flow rate with the use of a pressure controller. The pressure controller uses pressure targets based upon occlusion limits that are calculated as a function of flow. The controller has the ability to switch from controlling withdrawal pressure to controlling infusion pressure based upon the detection of an occlusion. The controller distinguishes between partial and total occlusions of the withdrawal vein providing blood access. Depending on the nature of occlusion, the controller limits or temporarily reverses blood flow and, thus, prevents withdrawal vessel collapse or reverses blood flow to quickly infuse blood into the vessel without participation from operator.

The present disclosure generally relates to techniques for managing a remote authorization to proceed with an action, such as creating a secure network connection. In some examples, a requesting device receives selection of one or more options. The requesting device transmits a request to proceed with an action to an authenticating device. The authenticating device concurrently displays an indication of the request to proceed with the action, information about the selected one or more options, and an indication of the requesting device. The authenticating device receives authorization to proceed with the action and transmits a response to the requesting device regarding the request to proceed with the action.

Inertial measurement units are subject to drift and noise characteristics that are normally distributed. While that drift and noise is problematic for inertial navigation, it is ideal for encryption key generation. The measurement values from an inertial measurement unit are random on several levels and can be used to effectively seed a pseudo random number generator for encryption key generation.

Active, aerodynamic controller that describes a method for dynamically controlling airflow using computer controlled movable air dams and airfoils on motor vehicles. It is well known that motor vehicles generally have a great deal of aerodynamic friction also known as drag. Fuel efficiency is greatly affected by a vehicle's aerodynamic drag. Aerodynamic drag is caused by both induced drag and parasitic drag. Parasite drag is somewhat fixed by the overall design and shape of a vehicle. Parasite drag is caused primarily by the laminar flow of air over the smooth surfaces of the vehicle's hood, roof, windows, side mirrors and door panels. Induced drag is much more variable and is primarily created by the differential pressure effects of air flowing over, under and around a vehicle, as well as the relative airflow caused by both ground effect and atmospheric air density and wind. This invention serves to actively minimize the effects of induced drag thus reducing the amount of fuel used by vehicles fitted with this invention.
