Abstract: An electronic device may have a housing in which a display is mounted. A gasket may be mounted in a groove between the display and housing. The gasket may contain an embedded stiffener. Corner brackets may be installed in the corners of the housing. The housing may have inner and outer concentric ribs. Recesses in the housing may be configured to receive the corner brackets. The recesses may be formed between the inner and outer concentric ribs. Gap filling structures such as a foam layer may be interposed between a rear housing wall and a display backlight unit. Display color variations may be corrected by using a backlight unit having an array of light-emitting diodes of different colors. An electrostatic discharge protection layer may be grounded to a housing using conductive tape. Black edge coatings and adhesive-based structures may block stray light. Camera window regions may be supported using adhesive.

Abstract: A charge circuit interrupt device comprises a ground fault interrupt module, a current generation module and a current injection module. The ground fault interrupt module disconnects a load from a charging source when a current imbalance exceeds a threshold. The current generation module generates a balancing current based on the current imbalance. The current injection module inputs the balancing current into the charging source to oppose the current imbalance. The charge circuit interrupt device may further include an input balance disable control module that disables the current generation module from generating the balancing current when the current imbalance exceeds the threshold, and a current isolation module that isolates the charging source and the ground fault interrupt module, the current generation module and the current injection module.

Abstract: A linear motor is provided including a magnet track including a plurality of permanent magnets, and a coil assembly including a plurality of laminations. The coil assembly defines a plurality of teeth having slots therebetween. The plurality of teeth include (1) two end teeth and (2) at least one non-end tooth arranged between the two end teeth. Each of the two end teeth defines an end profile including a first surface and a second surface. The first surface and the second surface are separated by a step which is substantially perpendicular to a plane defined by the plurality of magnets. The linear motor also includes a plurality of coils at least partially disposed in at least a portion of the slots defined by the plurality of teeth.

Abstract: A device for modifying an input signal having an input signal frequency and a duty cycle is disclosed. The device determines two separate counts for each of the high and low pulses of the input signal. One of the two counts for each of the high and low pulses is divided. The divided count is then compared with the undivided count. Based on this comparison, an output module outputs an output signal that has the same duty cycle as the input signal but at a frequency that is a multiple of the input signal frequency.

Abstract: A safety syringe comprising a casing having a neck and a plunger having a distal portion, a weak portion, and a coupling portion covered by a hollow stopper having a membrane. The plunger is channeled in the casing and is moveable between an extended position and a compressed position. A needle holder, in the neck, contains a distally facing arrowhead and a proximally facing needle. Moving the plunger from an extended position to a compressed position, causes the arrowhead to puncture the membrane and engage the coupling portion. If the plunger is returned to the extended position, the needle is drawn into the casing and the distal portion of the plunger can be removed. If the plunger is re-compressed, the needle encounters a wall in the neck preventing the needle from exiting the casing. The syringe is easy to manufacture and prevents manufacturing burrs from being injected into patients.
