A security system control panel or home automation control panel including an end-user replaceable cellular telephony module that is removable from the control panel without disassembling the control panel. The cellular module includes a body, a cellular telephony circuit coupled to the body, a cellular telephony antenna coupled to the body and the cellular telephony circuit, and a first connector coupled to the cellular telephony circuit and the body, wherein the first connector is sized and shaped or otherwise configured to be removably engaged by the end-user with a second connector in the control panel.

A dryer vent monitor device includes a temperature sensor coupled to a dryer exhaust pipe to measure a temperature inside the dryer exhaust pipe. A differential air pressure sensor is coupled at an input connection between a dryer and the exhaust pipe and at an output connection between the dryer exhaust pipe and an outdoor vent. The differential air pressure sensor measures a differential air pressure between the input connection and the output connection. A transceiver communicates with a monitoring system registered with the dryer vent monitoring device. The dryer vent monitoring device compares both the temperature and the differential air pressure with a preset threshold, determines that at least one of the temperature and the differential air pressure exceed the preset threshold, and generates an alert signal in response to determining that at least one of the temperature and the differential air pressure exceed the preset threshold.

A wireless communication device includes a housing including a front, a rear, a top, a bottom, a left side, and a right side, and a printed circuit board carried by the housing and carrying electronics for operation of the wireless communication device. The printed circuit board defines a plane, and a socket is disposed in the housing and connected to the circuit board. The socket is configured to allow substantially perpendicular receipt of a removable memory device relative to the plane defined by the printed circuit board, in a manner such that the socket defines a plane substantially perpendicular to the plane defined by the printed circuit board.

A tape cartridge has a front face sized for compatibility with an industry standard tape drive, and has sides longer than the sides of some industry standard cartridges. The sides and top of the housing extend outwardly in width to form a back portion of the cartridge that is wider than the front portion and prevent the cartridge from being inserted into non-compatible tape drives. Two large diameter tape hubs improve the empty hub to full pack diameter ratios, and improve the resulting tangential drive force and tape tension profiles as the tape moves between the hubs. Flanges are permanently bonded to the hubs to prevent the tape packs from shifting and a spring biases the hubs against the baseplate. A back set of rollers includes a high-drag roller that engages the drive belt at a fixed wrap angle and produces a relatively constant drag. A front set of rollers includes a drive roller and has rollers mounted to form substantially equal geometries with rollers in the back set respective to the tape hubs. The constant wrap angle of the high-drag roller tends to outweigh varying drags from other rollers, causing less change in tape tension and tangential drive force as the tape is transferred from hub to hub. A door covers the capstan and media access openings in the front face of the cartridge when the cartridge is outside of a tape drive. A write protect arm is pivotally mounted at the front face of the cartridge.

A tape cartridge has a baseplate surrounded by a housing. Two hub pins are disposed within the housing substantially perpendicular to the baseplate. Each pin has top and bottom portions and a collared portion therebetween. The bottom portion of each pin is press-fitted into a mating aperture in the baseplate with the collared portion bearing against the baseplate. A large diameter tape hub is rotatably mounted on the top portion. The collared portions allow the hub pins to withstand heavy side loads without significantly deflecting from the perpendicular. Two large diameter tape hubs are rotatably mounted around the hub pins and improve the empty hub to full pack diameter ratios, and improve the resulting tangential drive force and tape tension profiles as the tape moves between the hubs. A back set of belt rollers includes a high-drag roller that engages the drive belt at a fixed wrap angle and produces a relatively constant drag. A front set of belt rollers includes a drive roller and has rollers mounted to form substantially equal geometries with rollers in the back set relative to the tape hubs. The constant wrap angle of a drive belt on the high-drag roller tends to outweigh varying drags from other rollers, causing less change in tape tension and tangential drive force as the tape is transferred from hub to hub in response to movement of the drive belt along a path in contact with the drive roller, the belt rollers, and the tape on the hubs.

A tape guide for operation in contact with the back side of magnetic tape exhibits an increase in the coefficient of friction between the tape guide and the tape with increased wear of the guide surface associated with repeated passes of tape in sliding engagement over the tape contacting surface of the guide. The resulting increased frictional drag on magnetic tape with wear of the tape guide improves overall performance by reducing instantaneous speed variations (ISV) in the tape attributable to translational vibrations in the tape over the life of the tape and tape guide. The tape contacting surface of the tape guide includes a metal alloy including copper zinc, nickel and lead that may be integrally incorporated into the tape guide or plated thereon at least in the tape contacting region thereof.
