Abstract: A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base, a stabilizing element extending axially from the base, and a movable engagement element partially contained within the stabilizing element. The stabilizing element includes a first end adjacent the base and a second end opposite the first end. The movable engagement element extends from the first end of the stabilizing element to the second end of the stabilizing element. The movable engagement element is movable between an unlocked configuration, in which the movable engagement element is closer to the stabilizing element and the locking head is insertable into the portable electronic device, and a locked configuration, in which the movable engagement element is further from the stabilizing element and the locking head is secured to the portable electronic device.

Abstract: A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base and a compressible element supported by the base. The locking head is adjustable between an unlocked configuration, in which the compressible element is uncompressed and insertable into and removable from an opening of the portable electronic device, and a locked configuration, in which the compressible element is compressed and secured within the opening of the portable electronic device.

Abstract: A system for detecting/quantifying the conductance of a right-to-left cardiac shunt includes a mouthpiece assembly, a solenoid-driven vacuum/pressurization assembly; a controller for operating the solenoid-driven vacuum/pressurization assembly; and a monitor for displaying the instructions from the controller. A microbubble counting cell and digital image sensor are combined with software-based image analysis to determine a number of microbubbles contained in a microbubble counting zone. A monitor enables operator specification of total volume of contrast agent to be injected into the patient. One or more first Doppler ultrasound transducer arrays are positioned adjacent to targeted intracranial arteries at one side of the skull or a pair of first Doppler ultrasound transducer arrays positioned adjacent to targeted intracranial arteries at both sides of the skull.

Abstract: A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base and a plurality of pillar structures extending from the base. The plurality of pillar structures is configured to be inserted into an aperture of the portable electronic device. The locking head also has a ball positioned within each of the plurality of pillar structures. The ball is extendable outwardly from a corresponding pillar structure to inhibit the locking head from being removed from the aperture. The locking head further has a linear movable structure positioned within each of the plurality of pillar structures and operable to selectively extend outwardly each ball from the plurality of pillar structures. The security apparatus also includes a security device attached to the locking head and configured to engage the immovable object.

Abstract: A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base and a first linear element extending from the base. The first linear element is configured to be inserted into the aperture of the portable electronic device. The locking head also has a movable engagement element coupled to an end of the first linear element opposite from the base. The movable engagement element is configured to be inserted into the aperture of the portable electronic device with the first linear element. The movable engagement element is movable to a position in which the movable engagement element is perpendicular to the first linear element to secure the locking head to the portable electronic device. The security apparatus also includes a security device attached to the locking head and configured to engage the immovable object.
