Abstract: A radio frequency (RF) tamper detector of an electronic device can offer improved chassis intrusion monitoring to protect the device from software and hardware-based tampering. The tamper detector can monitor RF noise levels in a first frequency band and in a second frequency band to calculate an RF noise level moving average for each frequency band. If the moving averages in both frequency bands exceed a RF noise threshold, the tamper detector can set a cover removal flag to indicate that a cover of the device housing has been removed. The tamper detector can cause the electronic device to lock or disable a system BIOS when cover removal is detected. Additionally, the electronic device can notify remote monitoring systems (e.g., operated by an IT administrator or warranty support center) to receive additional instructions to secure the device.

Abstract: A gait evaluating system including a processor is provided. The processor identifies whether a gait type of the user belongs to a normal gait, a non-neuropathic gait or a neuropathic gait based on step feature values of a user and walking limb feature values of the user.

The first auxiliary information indicates a potential sarcopenia of the user. The second auxiliary information indicates a dietary guideline for muscle building and muscle strengthening. The third auxiliary information shows a motion instruction video for regaining or maintaining muscle strength of the user.

Abstract: An EUV radiation light source generation apparatus includes a pump laser, at least one pulse shaping unit, a wavelength conversion unit, and a high-order harmonics generation unit. The pump laser provides a pulse laser radiation beam. Each pulse shaping unit conducts a spectrum extending operation and a phase compensation operation to the pulse laser radiation beam. The phase compensation operation makes multiple frequency components of the pulse laser radiation beam emitted by the pulse shaping unit to be substantially in phase. The wavelength conversion unit conducts a center wavelength conversion operation to the pulse laser radiation beam. The high-order harmonics generation unit receives the pulse laser radiation beam processed by the pulse shaping unit and the center wavelength conversion operation, and focuses the received pulse laser radiation beam to a high order harmonic generation medium to generate a high order harmonic radiation beam.

Abstract: A screwdriver includes a first section, a second section where a positioning groove is annularly formed, a sleeve member detachably disposed on the second section, and an engagement member disposed in the sleeve member. The sleeve member has a body with a through hole, a magnetic unit disposed in the through hole, and an accommodation groove adapted to accommodate the engagement member. When the second section and the sleeve member engage in position, the accommodation groove and the positioning groove meet to engage the engagement member with the positioning groove. The engagement between the second section and the sleeve member allows a gap to be formed between a screw head and the sleeve member while inserting the second section into a socket of the screw head, so the magnetic attraction exists without the contact between the sleeve member and the screw head for a firm engagement therebetween.

Abstract: A non-magnetic locking sleeve includes an engagement unit disposed in a body which includes a locking socket and a positioning groove. The locking socket is enclosed by a plurality of peripheral walls connected one after another for holding a fastener. The positioning groove is annularly recessed into the peripheral walls for receiving the engagement unit. Preferably, an intersection of two adjacent peripheral walls forms a recessed portion whereby the fastener is held by the peripheral walls more tightly while inserting into the locking socket. A periphery of the engagement unit can be formed with a rough surface or at least one engaging surface to increase a contact area between the engagement unit and the fastener. Accordingly, the fastener is firmly positioned by the locking sleeve to increase the stability of a following fastening operation executed by the fastener.

Abstract: An electronic device including a signal processing circuit, an acceleration sensor, and an edge sensor is provided. The electronic device has a device body. The signal processing circuit operates in a sleep mode. The acceleration sensor senses an acceleration variation of the device body to generate an acceleration sensing signal. The acceleration sensor determines whether the acceleration sensing signal is continuously lower than an acceleration threshold for a preset length of time to wake up the signal processing circuit. When the acceleration sensor wakes up the signal processing circuit, the signal processor enables the edge sensor. The edge sensor senses a deformation variation of the device body to generate at least one deformation sensing signal. The signal processing circuit analyzes the deformation sensing signal to determine whether a drop event of the device body occurs. In addition, a drop warning method is also provided.

Abstract: A method for forming a wrench end includes the steps of preparing a flat blank, initially press-forging at least one end of the blank to form a head with a wrench-shaped part and a hole on the blank, bending the head to form a curved section and a stretched section which are bent at different angles, and shaping the head by holding the curved section and the stretched section with a gripping apparatus and then pressing the hole of the head with a punch in order to subject the two sections to a squeezing force whereby the sections can have a denser interior structure and facilitate a final shaping of the head. The method facilitates a quick shaping of the wrench end and increases the efficiency of forming a wrench product.
