Three-dimensional semiconductor memory devices and methods of fabricating the same. The three-dimensional semiconductor devices include an electrode structure with sequentially-stacked electrodes disposed on a substrate, semiconductor patterns penetrating the electrode structure, and memory elements including a first pattern and a second pattern interposed between the semiconductor patterns and the electrode structure, the first pattern vertically extending to cross the electrodes and the second pattern horizontally extending to cross the semiconductor patterns.

A soft start circuit generates a soft start voltage which changes over time when light emission of an EEFL is started. A pulse modulator receives a feedback voltage that corresponds to the output voltage of an inverter and the soft start voltage, and adjusts the duty ratio of a pulse signal PWM such that these two voltages match one another using a feedback operation. A striking control circuit monitors an error signal which is asserted when an abnormal state occurs. In a case in which the error signal has been asserted at a detection timing after the soft start voltage has reached a target voltage, the striking control circuit resets and restarts the soft start circuit. A driver controls the switching of the voltage at the primary coil of a transformer according to the pulse signal received from the pulse modulator.

A method, system, and apparatus for providing a self-destructing e-mail messages are described. An e-mail client application provides a user interface through which the sender of an e-mail message can enter the message and a time period for destruction of the message. Once the sender has provided this information, the e-mail client application sends a request to an e-mail server application to transmit the self-destructing e-mail message. The e-mail client application may also receive self-destructing e-mail messages. When a self-destructing e-mail message is received, the destruction date associated with the e-mail message is identified and the message is destroyed at the specified time. The e-mail client application can also limit the number and type of operations that may be performed on a self-destructing e-mail. An e-mail server application is also provided that receives requests from the e-mail client application to transmit self-destructing e-mail messages and perform other functions.

An efficient, low-loss, low sidelobe, high dynamic range phased-array radar antenna system is disclosed that uses metamaterials, which are manmade composite materials having a negative index of refraction, to create a biconcave lens architecture (instead of the aforementioned biconvex lens) for focusing the microwaves transmitted by the antenna. Accordingly, the sidelobes of the antenna are reduced. Attenuation across microstrip transmission lines may be reduced by using low loss transmission lines that are suspended above a ground plane a predetermined distance in a way such they are not in contact with a solid substrate. By suspending the microstrip transmission lines in this manner, dielectric signal loss is reduced significantly, thus resulting in a less-attenuated signal at its destination.

Mechanisms have been developed for securing computational systems against certain forms of attack. In particular, it has been discovered that, by maintaining and propagating taint status for memory locations in correspondence with information flows of instructions executed by a computing system, it is possible to provide a security response if and when a control transfer (or other restricted use) is attempted based on tainted data. In some embodiments, memory management facilities and related exception handlers can be exploited to facilitate taint status propagation and / or security responses. Taint tracking through registers of a processor (or through other storage for which access is not conveniently mediated using a memory management facility) may be provided using an instrumented execution mode of operation. For example, the instrumented mode may be triggered by an attempt to propagate tainted information to a register. In some embodiments, an instrumented mode of operation may be more generally employed. For example, data received from an untrusted source or via an untrusted path is often transferred into a memory buffer for processing by a particular service, routine, process, thread or other computational unit. Code that implements the computational unit may be selectively executed in an instrumented mode that facilitates taint tracking. In general, instrumented execution modes may be supported using a variety of techniques including a binary translation (or rewriting) mode, just-in-time (JIT) compilation / re-compilation, interpreted mode execution, etc. Using an instrumented execution mode and / or exception handler techniques, modifications to CPU hardware can be avoided if desirable.

Charging service vehicle networks are among the embodiments disclosed herein, including battery module-powered EV charging roadside service vehicles. Battery modules are removably mounted to the service vehicles and manually exchanged within a system of battery module storage locations. Some embodiments provide resupply vehicles for delivering battery modules between storage locations and / or service vehicles, and may be used to exchange battery modules. Controllers are used to reserve battery modules at the storage locations to ensure availability for high priority activities. Some storage locations have charging apparatus to recharge battery modules stored there, and some storage locations are repositionable mobile units. Multiple tiers or levels of system controllers used by service vehicles to control centers are implemented to manage operations and optimize usage of battery modules and charging services across wide areas, including providing additional service vehicles to supply temporary needs for charging services.

Methods, systems and computer program products which provide secure updates of firmware (i.e. data stored in a programmable memory device of a processing system) are disclosed. Updates of a programmable memory of a device may be controlled by providing an update window of finite duration during which the programmable memory may be updated. Access to the programmable memory may be based on the state of an access latch. The access latch may be set to allow access after a hardware reset of the device. An update control program may be executed to control access to the programmable memory and the latch reset to prevent access upon completion of the update control program. Verification of the update may be provided through encryption techniques and rules incorporated in certificates for application of updates to provide for selectively updating devices. Also disclosed are methods of securely providing differing functionality to generic devices.

A method for writing data in a non volatile memory unit having memory pages includes a predetermined number of memory cells storing a memory word being a predetermined sequence of digital values. An erase operation erases the memory words in the memory page, setting the predetermined sequence of digital values to a sequence of complementary values. A program operation stores in the memory cell a word and sets a sequence of a word to be stored. For the memory cells of the memory page, the memory word is compared with the word to be stored. A positive check is returned if complementary values of the sequence correspond to complementary values of the predetermined sequence. If the check is negative, the erase operation is executed. The memory word is compared with the word to be stored and the program operation is executed if the word to be stored is different.

A wireless local area network (WLAN) radio-frequency identification (RFID) tag system provides location finding in a wireless local area network (WLAN), using a WLAN channel. Interference with the WLAN is prevented by either using a sniffer circuit to determine that no network transmission is in progress, using a modified coding sequence or preamble to cause standard WLAN receivers to ignore the RFID tag transmissions, or transmitting a message using a standard WLAN signal addressed to an address not corresponding to a unit within the WLAN. Location units (LUs) and a master unit (MU) within the WLAN receive the RFID tag transmissions and can determine the location of a tag by triangulation based on differences between the signals received at the location units from the tag. The master unit receives the signal information from the location units and computes the location of the tag. Time-difference-of-Arrival (TDOA), received signal strength indication (RSSI) or other triangulation techniques may be used.
