Maintenance technicians at industrial plants are having a very unsafe year. The rates of fatal injuries at plants for maintenance and engineers is greater than five times greater the average. Long hours, stress, and a rush to get things done faster by supervision is creating an unsafe work condition. Flight engineers are also in the [...] Nylon (Poly-amide), invented in 1928 by Wallace Carothers (DuPont) is considered to be the first engineering thermoplastic. It is one of many hetero chain thermoplastics which has atoms other than C in the chain. Nylon is created when a condensation reaction occurs between amino acids, di-basic acids and di-amines. Commercially Nylon is commonly used in [...] Delrin® has excellent dimensional stability and high mechanical strength and stiffness. As a strong Polymer, Delrin® provides good wear and abrasion resistance, a low coefficient of friction and low moisture absorption, making the product a good choice for use in high moisture environments. Delrin® is an excellent choice for its long term mechanical stability in [...] Acetal became commercially available in 1960. Acetal is a by-product of a two-step reaction between an alcohol and an aldehyde. Formed by polymerizing anhydrous formaldehyde to form an oxymethlylene chain. Acetal is a popular and versatile crystalline engineering polymer. It is very strong and exhibits good chemical resistance. Acetal is a tough material with good [...] ABS resins are available in a wide range of melt flow rates, impact, tensile and flex strength and heat resistance for a wide variety of high and low gloss injection molding applications. The product demonstrates good mechanical properties and resistance to chlorine.. ABS’s light weight and ability to be injection molded and extruded make it [...] CPU Broadcom BCM4718 CPU Speed 480 MHz Flash ROM 16 MB Macronix MX25L12845E RAM 64 MB Radios 2.4 GHz, 5 GHz WLAN Support a/b/g/n WLAN Max Speed 300mbps (2.4 GHz) & 450mbps (5 GHz) Antenna Location Internal (x6) Bands 3 x 3 Switch 4x GigE + 1 WAN Broadcom 53115 IEEE 802.3/3u/3ab USB 1x [...] Security experts have examined the SIMATIC S7-1200 Programmable Logic Controller (PLC). This research has revealed some weaknesses in the SIMATIC S71200 CPU communication and authentication functions. Once the automation network is compromised it is possible to demonstrate the following weaknesses using a remote exploit: • Trigger CPU functions by record and playback of legitimate network [...] No one will ever follow a leader who isn’t credible. But how do you earn “credibility”? Here are some things to think about . . . Core Competency The first thing followers demand is a core competence, usually a high level of technical skill in a given area. Few Engineers will respect a leader [...] |
