A portable electric nailing gun operating from a power supply. The motor accelerates a flywheel, which at the appropriate energy state is coupled through a mechanism to an anvil acting directly on the nail. The actuation is governed by a control circuit and initiated from a trigger switch. The stored energy delivered from the motor is coupled to the output anvil drives the nail. At least one position of the output anvil is sensed and once the nail is driven, the power is disconnected from the motor. This method uses a direct acting clutch and a harmonic motion nailing mechanism to reduce wear and increase robustness of the nailer.

The energy status indicator gives a user control over when the energy status is to be output and also to the type of alert that is to be output (e.g. sound, vibration, etc.). Additionally, it allows the user to determine the energy status when visual inspection of the portable device is not possible.

A portable electric nailing gun operating from a power supply. The motor accelerates a flywheel which at the appropriate energy state is coupled through a mechanism to an anvil acting directly on the nail. The actuation is governed by a control circuit and initiated from a trigger switch. The motor accelerates a flywheel that is then clutched to the output anvil causing the nail to be driven. The position of the output anvil is sensed and once the nail is driven, the motor is dynamically braked reducing the excess energy in the flywheel. This method uses a highly responsive motor and power supply which enables the motor to come up to speed, drive the nail and return to a low energy condition in less than 2 seconds. The electrical control circuit and brake allow precise control and improve safety. The power supply is preferably a rechargeable low impedance battery.

A vaso-occlusive device includes a microcoil formed into a minimum energy state secondary configuration comprising a plurality of curved segments, each defining a discrete axis, whereby the device, in its minimum energy state configuration, defines multiple axes. In a preferred embodiment, the secondary configuration-comprises a plurality of interconnected closed loops defining a plurality of discrete axes. In a second embodiment, the secondary configuration defines a wave-form like structure comprising an array of laterally-alternating open loops defining a plurality of separate axes. In a third embodiment, the secondary configuration forms a series of tangential closed loops, wherein the entire structure subtends a first angle of arc, and wherein each adjacent pair of loops defines a second angle of arc. In a fourth embodiment, the secondary configuration forms a logarithmic spiral. In all embodiments, the device, in its secondary configuration, has a dimension that is substantially larger than the largest dimension of the vascular site (i.e., aneurysm) in which it is to be deployed. Thus, confinement of the device within an aneurysm causes it to assume a three-dimensional configuration with a higher energy state than the minimum energy state. Because the minimum energy state configuration of the device is larger (in at least one dimension) than the aneurysm, the deployed device is constrained by its contact with the walls of the aneurysm from returning to its minimum energy state configuration. The engagement of the device with the aneurysm wall minimizes shifting or tumbling due to blood flow. Furthermore, the secondary configuration is not conducive to “coin stacking,” thereby minimizing the compaction experienced.

A method of screening EEPROMs for data retention quality employs a UV source which is arranged to be impinged upon the devices while in wafer form, at or near an electrical probe station. Known data is stored in memory cells on an EEPROM chip while the chip is in wafer form, at a probe station. The wafer is then moved beneath a UV silo near the probe station and exposed to UV light, for a period of time and at an intensity which is sufficient to cause leakage of charge from potentially leaky floating gates. The wafer is again subjected to electrical probe where the amount of change in retained charge is detected. From this test, an indication of the charge retention ability of the devices is obtained. The UV light increases the energy state of the stored charge thus accelerating the decay of the stored charge located on the floating gates in the EEPROM device. Bits that have inherent leakage paths decay more rapidly.

A microcoil vaso-occlusive device has a minimum energy state secondary configuration having a plurality of curved segments, each defining a discrete axis. The secondary configuration may be a plurality of interconnected closed loops; an array of laterally-alternating open loops; a series of tangential closed loops; or a logarithmic spiral. The device, in its secondary cofiguration, has a dimension that is substantially larger than the largest dimension of the vascular site in which it is to be deployed.
