Solving the distal reward problem through linkage of STDP and dopamine signaling
In Pavlovian and instrumental conditioning, rewards typically come seconds after reward-triggering actions, creating an explanatory conundrum known as the distal reward problem or the credit assignment problem. How does the brain know what firing patterns of what neurons are responsible for the reward if (1) the firing patterns are no longer there when the reward arrives and (2) most neurons and synapses are active during the waiting period to the reward? A model network and computer simulation of cortical spiking neurons with spike-timing-dependent plasticity (STDP) modulated by dopamine (DA) is disclosed to answer this question. STDP is triggered by nearly-coincident firing patterns of a presynaptic neuron and a postsynaptic neuron on a millisecond time scale, with slow kinetics of subsequent synaptic plasticity being sensitive to changes in the extracellular dopamine DA concentration during the critical period of a few seconds after the nearly-coincident firing patterns. Random neuronal firings during the waiting period leading to the reward do not affect STDP, and hence make the neural network insensitive to this ongoing random firing activity. The importance of precise firing patterns in brain dynamics and the use of a global diffusive reinforcement signal in the form of extracellular dopamine DA can selectively influence the right synapses at the right time.

Pixels of a detected blob are segmented for calculation of a centroid using a blob-separation threshold which is the average intensity around the closed curve of the determined size. The technique allows accurate and rapid detection of blobs of the predetermined shape.

Authenticity verification of articles using a database
A digital-signature is obtained by digitising a set of data points obtained by scanning a coherent beam over a paper, cardboard or other article, and measuring the scatter. A thumbnail-digital signature is also determined by digitising an amplitude spectrum of a Fourier transform of the set of data points. A database of digital signatures and their thumbnails can thus be built up. The authenticity of an article can later be verified by re-scanning the article to determine its digital signature and thumbnail, and then searching the database for a match. Searching is done on the basis of the Fourier transform thumbnail to improve search speed. Speed is improved, since, in a pseudo-random bit sequence, any bit shift only affects the phase spectrum, and not the amplitude spectrum of a Fourier transform represented in polar coordinates. The amplitude spectrum stored in the thumbnail can therefore be matched without any knowledge of the unknown bit shift caused by registry errors between the original scan and the re-scan.

Semiconductor device package with internal device protection
An integral impedence is formed on or within a lead frame pin of a semiconductor package and receives a connection from an electrode of a semiconductor die within the package to eliminate the need for adjustment and protective impedences external of the package. The impedence comprises passives such as resistors, capacitors, diodes or inductors which modify the performance of the package for new semiconductor device characteristics. The impedences may have positive or negative temperature coefficients and are in close thermal communication with the semiconductor die.
Method and apparatus for spatially optimizing surface mount pads on a ball grid array package
Method and apparatus for spatially optimizing the arrangement of surface mount pads on a ball grid array package. An array containing T surface mount pads with a diameter less than or equal to 0.4 millimeter is arranged in an array of rows and columns less than or equal to 0.5 millimeters center-to-center. The array of pads is subdivided into N groups of pads respectively numbered Gx (for X from 1 to N), each group containing Px pads (for X from 1 to N). Each pad in each group is located so as to maximize the number of empty spaces Sz that are adjacent to each pad, where Sz=(Gx−1). The number of fanout possibilities for each group (Px*Sz) is calculated, and then the total number of fanout possibilities, FP, is calculated using the function Σ1N (Px*Sz). The resulting spatially optimized pattern has a quality score, FP/T, that is equal to or greater than 2.
USB package with bistable sliding mechanism
A USB device including a bistable mechanism that serves to bias a plug connector into one of two stable states, where the first stable state is associated with a retracted position in which the plug connector is fully retracted inside a housing, and the second stable state is associated with a deployed position in which the plug connector extends through the front opening for coupling to a host system. Movement of the plug connector form the retracted to the deployed position is performed by manually applying a force to a handle portion that protrudes through a slot defined in the housing. The bistable mechanism resists the deploying force until an equilibrium point is reach, after which the bistable mechanism releases stored potential energy to complete the deploying process and to maintain the plug connector is the deployed position.
Multi-layer printed wiring board, electronic device, and fabrication method of electronic device
There is provided a multi-layer printed wiring board that can perform impedance control, concurrently maintaining the flexibility of a flexible portion with one or more signal lines. Such a multi-layer printed wiring board includes a plurality of rigid board units; and a flexible board unit, connecting outer layers or inner layers of the plurality of rigid board units and extending over the outer layers or the inner layers of the plurality of rigid board units. The flexible board unit includes a signal layer sending signals between the plurality of rigid board units; ground layers sandwiching the signal layer; and intermediate layers each interposed between the signal layer and one of the ground layers.
Micro-SD to secure digital adaptor card and manufacturing method
A microSD-to-SD adaptor card includes a base substrate having a lead frame structure, a protective cap forming a chamber that encloses eight microSD contact pins of the lead frame structure, and a thermoset plastic casing formed over the protective cap and exposed portions of the base substrate to provide the adaptor card with standard SD card dimensions. A rear opening facilitates insertion of a standard microSD card, whereby the eight contact pads on the microSD card are contacted by the eight microSD contact pins inside the chamber to allow electrical signals generated by the microSD card to be transmitted to a host system by way of a standard SD socket. A grip anchor pin is disposed inside the chamber to engage a grip notch disposed on the microSD card. A pre-molded switch slot is provided on the molded plastic casing, and an insert-in write protect switch is mounted after molding.
Provided is a circuit device capable of increasing the packaging density and preventing the thermal interference between circuit elements to be incorporated. In a hybrid integrated circuit device, a first circuit board and a second circuit board are fitted into a case member in a way that the first circuit board is overlaid with the second circuit board. A first circuit element is arranged on the upper surface of the first circuit board and a second circuit element is arranged on the upper surface of the second circuit board. Furthermore, inside the case member, provided is a hollow portion that is not filled with a sealing resin. Such a configuration prevents the second circuit element, which is a microcomputer, from operating unstably due to a heat generated in the first circuit element, which is a power transistor, for example.
