Computer-implemented methods for valuing a derivative based on the BMA rate: the methods may comprise generating a model of the BMA/LIBOR ratio as a function of the LIBOR index, a stochastic noise function, and a seasonality process. The methods may also comprise solving the model for at least one value of the LIBOR index, and estimating a value of the derivative given the solution of the model. The value of the derivative may then be stored.

A sunglass holder is removably clamped on a sunvisor in a car for fastening a pair of sunglasses or eyeglasses on the sunglass holder when not in use, and an illuminator such as a LED illuminator is detachably attached to the sunglass holder. The illuminator may be easily removed from the sunglass holder for portable illumination use.

A manufacturing method makes memory modules from partially-good DRAM chips soldered to its substrate. The partially-good DRAM chips have a number of defective memory cells that is below a test threshold, such as 10%. Packaged DRAM chips are optionally pre-screened and considered to pass when the number of defects found is less than the test threshold. A defect table is created during testing and written to a serial-presence-detect electrically-erasable read-only memory (SPD-EEPROM) on the memory module. The memory module is finally tested on a target-system tester that reads the defect table during booting, and redirects memory access to defective memory locations identified by the defect table. The memory modules may be burned in or tested at various temperatures and voltages to increase reliability.

An alarm device for a notebook, including a housing, a circuit board, a press key module, a sensing unit and an alarm unit. The housing is a flat housing. A bottom face of the housing is attachable to a surface of the notebook. An upper section of the housing is formed with an arced edge. The press key module is arranged on the surface of the housing for a user to operate to generate control signals. The circuit board, the sensing unit and the alarm unit are arranged in the housing. The sensing unit serves to sense respective tilting or vibration states and output a sensing signal to the circuit board. The circuit board includes various related electronic components and a rechargeable battery for supplying power for the circuit board. The circuit board serves to accept the control signals from the press key module and the sensing signals from the sensing unit and output an alarm signal to the alarm unit. The alarm unit serves to accept the alarm signal from the circuit board to produce alarm sound/light.

A mobile stabilizing seat is composed of a seat body, a driving stabilizing set, and a cover. The seat body is provided with a block partitioned into containing slots at a periphery of the block, and a periphery of the seat body is formed with a plurality of opening slots. The driving stabilizing set is mobile assembled with a gear on the seat body, and the gear is gnawed with a plurality of stabilizing members below each of which is provided with a pillar. Each pillar is sheathed with an elastic member which is one end transfixed into the containing slot partitioned at the periphery of block, for enabling each stabilizing member to be mobile stabilized. The cover is assembled on the seat body. Accordingly, the mobile stabilizing seat proves a design of perfect driving and robust stabilizing, which is easily and quickly assembled, firmly stabilized, and used conveniently.

A downgraded memory module has downgraded DRAM chips soldered to its substrate. The downgraded DRAM chips have a defective memory cell in a logical quadrant of the memory. A physical MSB is a row address present on a non-downgraded DRAM of size S but not used on a downgraded DRAM size S/2. The physical MSB and a second address pin are non-multiplexed address pins that do not carry column addresses. The physical MSB and the second address pin logically divided the DRAM into quadrants. Two good quadrants without defects are selected, and jumpers on the memory module drive the physical MSB and the second address pin with signals that select only these two quadrants and disable access to quadrants containing defects. DRAM chips can be marked or sorted into bins for combinations of good quadrants. Downgraded memory modules have all DRAM chips from the same bin that share jumper settings.

An armlet-type alarm includes a main body having a control circuit and a buzzer mounted therein, and a length-wise adjustable fastening band connected to the main body. The main body is provided at a top with a large-sized alarm push button assembly having a light-emitting device located therein, and a light-up switch for actuating the light-emitting device to emit light intermittently. One side of the main body includes a sound box, which uses a user's arm as one sidewall thereof and has a plurality of sound apertures provided therein. The armlet-type alarm may emits an intermittent warning light if so desired, and may be caused to emit a loud sound in an emergency simply by clapping the alarm push button assembly to actuate the buzzer inside the main body of the alarm.
